What Is Lost Filling Repair and How Can Dentemp Help?

 

Losing a filling is more common than you might think. It can happen when you're eating, biting down on something hard, or simply over time as old dental work wears out. When it does, the exposed tooth can become incredibly sensitive to hot, cold, and sweet foods — and waiting days for a dentist appointment can feel unbearable. That's exactly where lost filling repair products like Dentemp come in. Available from our dental products range at Cured Pharmacy, this kit gives you a practical, temporary solution you can use at home while you arrange professional care.

Dentemp Lost Filling Dental Repair provides over 14 individual repairs per pack, making it one of the more cost-effective temporary dental kits available over the counter. At just £5.99, it's a sensible first step when dental pain strikes unexpectedly. It won't replace your dentist — nothing will — but it can meaningfully reduce discomfort and protect the exposed tooth surface in the short term.

 

How Does Dentemp Lost Filling Dental Repair Work?

 

Dentemp uses a calcium sulphate-based, eugenol-free formula that sets when it comes into contact with moisture in your mouth. The material is mouldable before it hardens, which means you can press it into the cavity and shape it to match your bite. Once set, it forms a temporary protective layer over the exposed dentine and pulp area, reducing sensitivity and helping to keep bacteria out.

  • The material is applied directly into the cavity or over the affected area
  • Saliva triggers the setting process — no mixing required
  • It hardens within a few minutes of application
  • The eugenol-free formula reduces the risk of irritation for those sensitive to clove-based compounds
  • Once set, it acts as a physical barrier against temperature changes and food debris

It's worth noting that Dentemp is not designed to bond permanently to tooth structure. Think of it as a protective cap rather than a true restoration. The NHS advises that any lost filling should be assessed by a dentist as soon as possible, even if temporary measures have been taken.

 

Who Should Use Dentemp Lost Filling Dental Repair?

 

This product is suitable for adults and older teenagers who have lost a filling, crown, or inlay and are waiting for a dental appointment. It's particularly useful in situations where dental access is limited — for example, over a bank holiday weekend, when travelling, or during a period of dental waiting list delays. It can also offer short-term relief for a chipped or cracked tooth surface.

  • Adults aged 18 and over with a lost or dislodged filling
  • People experiencing tooth sensitivity due to an exposed cavity
  • Those awaiting a dental appointment who need interim protection
  • Travellers or individuals in areas with limited dental access

It is not suitable for children under 12 without dental supervision, and it should not be used as a substitute for professional dental care under any circumstances.

 

How Does Dentemp Compare to Other Temporary Dental Repair Options?

 

Feature Dentemp Lost Filling Repair Generic Zinc Oxide Paste
Number of repairs per pack 14+ Varies (typically 5–10)
Eugenol-free formula Yes Often contains eugenol
Setting mechanism Moisture-activated Chemical cure (mixing required)
Ease of use Ready to use, no mixing May require two-component mixing

 

Is Dentemp Suitable for All Teeth and How Should It Be Stored?

 

Dentemp can be used on most teeth, including molars and premolars where fillings are most commonly lost. However, it is not recommended for use on front teeth where aesthetics are a concern, as the material is not tooth-coloured in the same way as composite resin. If you're managing lost filling repair on a visible front tooth, speak to your dentist about the most appropriate interim option. You can also browse our oral health collection for complementary products to support your dental care routine.

Store Dentemp below 25°C in a cool, dry place away from direct sunlight. Keep the lid tightly closed between uses to prevent the material from drying out prematurely. Keep out of reach of children.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Dentemp Lost Filling Dental Repair and What Is It Used For?

 

Dentemp Lost Filling Dental Repair is an over-the-counter temporary dental filling material used to provide short-term protection when a filling, crown, or inlay has been lost or dislodged. It is not a permanent dental treatment. Its purpose is to reduce tooth sensitivity, protect the exposed cavity from bacteria and food debris, and provide comfort while you wait for a professional dental appointment. The NHS recommends contacting your dentist as soon as possible if you lose a filling, even if you have used a temporary repair product in the meantime.

This product is classified as a General Sale (GSL) medicine in the UK, meaning it can be purchased without a prescription. It is intended for temporary use only and should never be considered a long-term substitute for professional dental care. If you are also managing other aspects of your health, our pain relief collection includes products that may help manage associated dental discomfort while you await your appointment.

 

What Do You Need to Know Before Using Dentemp Lost Filling Dental Repair?

 

Before using this product, read the following contraindications and warnings carefully:

  • Do not use if you are allergic to any of the ingredients in the formula
  • Not recommended for children under 12 years of age without dental supervision
  • Do not use to treat dental abscesses, infections, or severe toothache — seek urgent dental or medical advice instead
  • Do not swallow the dental repair material
  • Avoid use if you have known sensitivity to calcium sulphate compounds
  • This product does not treat the underlying cause of a lost filling — professional dental assessment is essential
  • If pain worsens or swelling develops, stop use and contact your dentist or NHS 111 immediately

Regarding drug interactions, no significant interactions with systemic medicines have been identified for topically applied temporary dental filling materials. However:

  • If you are taking anticoagulants (blood thinners) and experience any gum bleeding, seek dental advice promptly
  • Inform your dentist of any medicines you are taking before your appointment, as some may affect dental treatment options

 

How Should You Use Dentemp Lost Filling Dental Repair?

 

Follow these steps carefully to apply Dentemp correctly and safely:

  1. Rinse your mouth thoroughly with water to clean the affected area
  2. Dry the tooth as much as possible using a clean tissue or cotton wool
  3. Remove a small amount of Dentemp material from the container using the applicator provided
  4. Press the material firmly into the cavity or over the affected tooth surface
  5. Bite down gently to shape the material to your natural bite — do not bite hard
  6. Allow the material to set for at least 2–3 minutes without eating or drinking
  7. Avoid eating or drinking for at least 60 minutes after application
  8. Replace the lid tightly on the container after use
Indication Age Group Amount to Use Frequency
Lost filling Adults (18+) Small pea-sized amount per cavity Reapply as needed until dental appointment
Lost filling 12–17 years Small pea-sized amount Under dental supervision only
Chipped tooth (temporary) Adults (18+) Small amount to cover exposed area Reapply if dislodged; see dentist promptly

 

What Are the Possible Side Effects of Dentemp Lost Filling Dental Repair?

 

Side effects with Dentemp are uncommon when the product is used as directed. However, as with any product applied inside the mouth, some people may experience reactions. Stop use and seek advice if you experience anything concerning.

Common side effects:

  • Mild gum irritation around the treated tooth
  • Temporary increased tooth sensitivity immediately after application
  • Slight taste alteration in the mouth

Less common side effects:

  • Localised soft tissue irritation if material contacts the gum excessively
  • Difficulty biting comfortably if the material is applied too thickly
  • Allergic reaction (rare) — signs include swelling, redness, or persistent pain

If you experience swelling of the face, lips, or throat, or have difficulty breathing, seek emergency medical attention immediately as this may indicate a serious allergic reaction.

Frequently Asked Questions

Where can I buy Dentemp Lost Filling Dental Repair online in the UK?

You can buy Dentemp Lost Filling Dental Repair directly from Cured Pharmacy online for just £5.99 with fast UK delivery. It is a General Sale (GSL) product, so no prescription is needed. Browse our full dental products range for other oral care essentials alongside your order.

How does Dentemp Lost Filling Dental Repair work in the mouth?

Dentemp uses a moisture-activated calcium sulphate-based formula that sets when it contacts saliva inside your mouth. Once applied to the cavity, it hardens to form a temporary protective seal over the exposed tooth surface. This helps reduce sensitivity to temperature and pressure while you wait for a professional dental appointment.

How do I use Dentemp Lost Filling Dental Repair step by step?

Start by rinsing and drying the affected tooth as thoroughly as possible. Press a small pea-sized amount of the Dentemp material into the cavity, then bite down gently to shape it to your natural bite. Allow it to set for 2–3 minutes and avoid eating or drinking for at least one hour after application.

How long does a Dentemp temporary filling last?

Dentemp is designed as a short-term temporary measure and may last anywhere from a few days to a couple of weeks, depending on the location of the tooth and your eating habits. Chewing hard or sticky foods can dislodge the material more quickly. It is not a permanent solution — you must see a dentist as soon as possible for a proper restoration.

Is Dentemp safe to swallow if it comes loose?

Dentemp is not intended to be swallowed, and you should take care to avoid ingesting the material during application. If a small amount is accidentally swallowed, it is unlikely to cause serious harm in adults, but you should contact NHS 111 or a healthcare professional for guidance if you are concerned. Keep the product away from children at all times.

Can I use Dentemp for a broken or chipped tooth?

Yes, Dentemp can provide temporary protection for a chipped or broken tooth by covering the exposed area and reducing sensitivity. However, it is not a structural repair and will not restore the strength of the tooth. You should contact your dentist promptly for a proper assessment and treatment plan.

What are the side effects of Dentemp Lost Filling Dental Repair?

Most people tolerate Dentemp well, but some may experience mild gum irritation, temporary tooth sensitivity, or a slight taste change after application. Allergic reactions are rare but possible — if you notice swelling, persistent pain, or redness, stop use immediately and contact your dentist or NHS 111. Serious allergic reactions require emergency medical attention.

Who is eligible to use Dentemp Lost Filling Dental Repair?

Dentemp is suitable for adults aged 18 and over who have lost a filling, crown, or inlay and need temporary relief while awaiting a dental appointment. It can be used in those aged 12–17 under dental supervision. It is not recommended for children under 12, and it should not be used to treat dental abscesses, infections, or severe toothache.

What happens if I use too much Dentemp material?

Applying too much material can result in an uneven bite, which may cause discomfort when chewing or put pressure on adjacent teeth. If this happens, carefully remove the excess material before it fully sets and reapply a smaller amount. If your bite feels significantly off after the material has hardened, contact your dentist for advice.

What are the alternatives to Dentemp for a lost filling?

Other temporary dental repair options available over the counter in the UK include zinc oxide-based pastes and products such as Cavit. However, the only permanent solution for a lost filling is professional dental treatment from a registered dentist. You can also find complementary products in our oral health collection to support your dental care between appointments.

Can Dentemp be used to reattach a lost crown?

Dentemp can be used as a temporary measure to hold a dislodged crown in place or to protect the underlying tooth if the crown cannot be reseated. It is not a dental adhesive and will not provide a permanent bond. Take the crown to your dentist as soon as possible so it can be properly recemented or replaced.

How many repairs does one pack of Dentemp provide?

Each pack of Dentemp Lost Filling Dental Repair provides 14 or more individual repairs, making it a cost-effective option for temporary dental emergencies. The number of uses will vary depending on the size of the cavity and how much material is applied each time. Storing the product correctly with the lid tightly closed between uses helps preserve the remaining material.

Is Dentemp eugenol-free and why does that matter?

Yes, Dentemp uses a eugenol-free formula. Eugenol is a clove-derived compound found in some dental materials that can cause irritation or allergic reactions in sensitive individuals. Choosing a eugenol-free product reduces this risk, making Dentemp a more comfortable option for people who have previously experienced sensitivity to traditional zinc oxide eugenol pastes.

How long can you keep using Dentemp before seeing a dentist?

Dentemp is strictly a temporary measure and should not be used as a long-term substitute for professional dental care. The NHS advises contacting your dentist as soon as possible after losing a filling, even if you have applied a temporary repair. Prolonged delay in seeking treatment can allow bacteria to reach the tooth pulp, potentially leading to infection or abscess.

What are the latest recommendations on managing a lost filling at home?

Current NHS guidance recommends contacting your dentist promptly if you lose a filling, and using an over-the-counter temporary dental repair product only as a short-term bridge until your appointment. Temporary filling materials like Dentemp can reduce sensitivity and protect the tooth, but they do not address the underlying cause of filling loss. If you are also experiencing pain, over-the-counter pain relief may help — see our pain relief range for suitable options.

How Should You Use Dentemp Lost Filling Dental Repair?

Using Dentemp correctly makes a real difference to how well it holds and how comfortable it feels. Before you start, make sure the affected tooth is as clean and dry as possible — moisture from saliva will trigger the setting process, so you want to control exactly when that happens. Work quickly once you have the material in place.

What Is the Correct Dose of Dentemp Lost Filling Dental Repair?

There is no fixed "dose" in the traditional sense, but using the right amount of material is important. Too little and the cavity won't be adequately covered; too much and your bite may feel uneven, causing discomfort when chewing. A pea-sized amount is sufficient for most standard cavities.

When Is the Best Time to Use Dentemp Lost Filling Dental Repair?

Apply Dentemp at a time when you can avoid eating or drinking for at least one hour afterwards — this gives the material the best chance to set properly. Many people find it easiest to apply after brushing their teeth in the evening, so the material can set undisturbed overnight. Avoid applying immediately before a meal or hot drink.

If the material becomes dislodged during eating, wait until you have rinsed your mouth and dried the tooth before reapplying. Never attempt to reapply while the tooth is wet with saliva, as this will prevent adequate adhesion.

How Long Can You Use Dentemp Lost Filling Dental Repair For?

Dentemp is strictly a temporary measure. It is not designed for long-term use and should not replace professional dental treatment. The NHS advises contacting your dentist as soon as possible after losing a filling, even if you have applied a temporary repair at home.

Prolonged use without seeking dental care can allow bacteria to penetrate the tooth, potentially leading to infection, abscess, or nerve damage — all of which are more complex and costly to treat. Use Dentemp only as a bridge to your next dental appointment, not as an ongoing solution.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Dentemp Lost Filling Dental Repair?

Most people use Dentemp without experiencing any significant side effects. However, because the material is applied inside the mouth, some mild reactions can occur, particularly in the first hour or two after application. These are usually short-lived and resolve on their own.

  • Mild gum irritation around the treated tooth
  • Temporary increased tooth sensitivity to hot or cold
  • Slight alteration in taste immediately after application
  • Minor discomfort when biting if the material is applied unevenly

What Are the Less Common Side Effects of Dentemp Lost Filling Dental Repair?

Less commonly, some individuals may experience reactions that are slightly more noticeable, particularly if the material contacts soft tissue in the mouth for a prolonged period. These are still generally mild and manageable.

  • Localised soft tissue irritation if excess material contacts the gum line
  • Difficulty achieving a comfortable bite if too much material is applied
  • Dry mouth sensation in the area around the treated tooth
  • Slight loosening of the material during eating, particularly with sticky or hard foods

What Are the Serious Side Effects of Dentemp Lost Filling Dental Repair?

Serious side effects are rare but possible. An allergic reaction to any component of the formula, though uncommon, can occur. Signs of a serious allergic reaction include swelling of the face, lips, tongue, or throat, difficulty breathing, or a widespread skin rash. If you experience any of these symptoms, stop use immediately and call 999 or go to your nearest A&E department without delay.

Persistent or worsening tooth pain after application may indicate an underlying dental infection or abscess, which requires urgent professional assessment. Do not attempt to manage a dental abscess with a temporary filling product.

What Should You Do If You Experience Side Effects of Dentemp?

For mild side effects such as gum irritation or sensitivity, simply remove any excess material from the gum line and rinse your mouth gently with lukewarm water. If sensitivity persists beyond 24 hours, contact your dentist for advice. For more significant reactions, stop use entirely and seek professional guidance from your dentist, pharmacist, or NHS 111.

Never ignore worsening pain, swelling, or fever following the use of any dental product, as these may indicate infection requiring antibiotic treatment or urgent dental intervention.

Can Dentemp Lost Filling Dental Repair Interact With Other Medicines?

No significant interactions between Dentemp and systemic medicines have been identified, as the product is applied topically inside the mouth and is not absorbed into the bloodstream in meaningful amounts. However, if you are taking anticoagulant medicines (blood thinners) such as warfarin and experience any gum bleeding during or after application, you should inform your dentist and GP. Always tell your dentist about all medicines you are currently taking before undergoing any dental procedure or treatment.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
