Tooth Filling Guide: Options, Innovations, and Patient Advice
A tooth filling is a common dental restoration used to repair damage from decay or minor injury, helping restore strength and prevent further issues.
Understanding Tooth Fillings: When and Why They’re Needed
A tooth filling repairs a tooth by replacing decayed or damaged tissue with a strong, restorative material. This helps prevent further deterioration, relieve discomfort, and restore normal chewing function.
You might need a filling if you have:
- Cavities (tooth decay)
- Cracks or chips from injury
- Worn teeth due to grinding or erosion
- Old or damaged fillings requiring repair or replacement
Early treatment helps avoid more serious problems such as infection or tooth loss. Your dentist will assess your tooth to determine if a filling is appropriate.
Types of Dental Fillings: Pros, Cons, and Best Uses
Different filling materials suit different needs. The best choice depends on the tooth’s location, your budget, and your priorities such as appearance or durability.
| Filling Material | Advantages | Drawbacks | Best For |
| Amalgam | Very strong and durable; cost-effective | Silver colour; contains mercury; restricted use for deciduous (baby) teeth, children under 15, pregnant or breastfeeding patients in the UK | Back teeth, high-pressure areas (adults) |
| Composite (White) | Tooth-coloured; bonds well to tooth structure; minimal drilling | May wear faster than metal; sometimes more costly | Front and visible teeth |
| Glass Ionomer | Releases fluoride; chemically bonds to tooth; gentle on tooth structure | Less durable; wears down sooner | Small cavities; children’s teeth |
| Ceramic/Porcelain | Highly aesthetic; stain-resistant; durable | Higher cost; may require more than one visit | Front and back teeth |
| Gold | Extremely durable; long lifespan | Expensive; noticeable colour | Molars; patients prioritising longevity |
Amalgam Safety and Restrictions
Amalgam fillings contain a mercury alloy, which is permitted under UK regulations for most adult cases. However, amalgam use is restricted for deciduous (baby) teeth, children under 15, and pregnant or breastfeeding patients, except where a dentist considers it strictly necessary based on the patient’s specific medical needs. Your dentist will discuss suitable alternatives if you fall into these groups.

How to Choose the Right Filling for You
Choosing the right filling involves considering several factors:
- Tooth location: Back teeth (molars) require strength; front teeth benefit from aesthetics.
- Budget: Some materials cost more due to durability, appearance, or technology.
- Appearance: Tooth-coloured options (composite, ceramic) blend in with natural teeth.
- Health considerations: Allergies are rare but alternatives are available if needed.
- Lifestyle: If you grind your teeth or chew hard foods, discuss the most robust options with your dentist.
If you are unsure, your dentist will guide you based on your clinical needs and preferences.

Innovations in Dental Fillings: What’s New?
Modern dentistry offers more comfortable, durable, and natural-looking fillings than ever before.
- CEREC Technology: At Mallards Dental Practice, CEREC technology for single-visit crowns allows ceramic restorations to be designed, made, and fitted in one appointment, reducing treatment time.
- Bioactive Materials: Some newer filling materials release minerals that may help protect teeth, though their use depends on individual cases.
- Anaesthesia with The Wand: Computer-controlled local anaesthesia with The Wand delivers anaesthetic precisely and gently, reducing discomfort from injections. While many patients find this improves comfort, individual experiences vary.
These advances can enhance your treatment experience and outcomes, ask your dentist what options are suitable for you.
What to Expect: The Tooth Filling Procedure & Recovery
A filling is usually straightforward and completed in one visit. The typical process includes:
- Assessment: The dentist examines your tooth and may take X-rays.
- Anaesthesia: Local anaesthetic is administered, often using The Wand system for greater comfort.
- Decay removal: Damaged tissue is carefully removed.
- Cavity preparation: The space is cleaned and shaped to hold the filling.
- Filling placement: The chosen material is placed, shaped, and set (often using a curing light).
- Finishing touches: The filling is polished and your bite is checked for comfort.
Aftercare and Recovery
- Numbness may last a few hours, avoid eating until sensation returns.
- Mild sensitivity to hot, cold, or pressure is common but usually subsides within days.
- Follow your dentist’s aftercare instructions carefully.
Contact your dentist if you experience severe pain, swelling, or if the filling feels rough or loose.
Caring for Your Filling: Immediate and Long-Term Tips
Proper care helps your fillings last and protects your overall dental health.
Aftercare Tips
- Brush twice daily with fluoride toothpaste.
- Clean between teeth daily using floss or interdental brushes.
- Avoid biting hard objects like ice, pens, or fingernails.
- Limit sugary snacks and drinks.
- Attend regular dental check-ups to monitor your fillings.
- If you grind your teeth, ask about a night guard to protect your restorations.
Immediately After a Filling
- Do not eat until numbness has worn off to avoid biting your cheek or tongue.
- Avoid very hot, cold, or chewy foods for several hours.
How Long Do Fillings Last?
- Amalgam and gold fillings often last 10–15 years or more.
- Composite and glass ionomer fillings typically last 5 – 7 years, depending on care and location.
- Ceramic fillings are durable, especially for visible teeth.
See your dentist if you notice pain, cracks, roughness, or if a filling feels loose or falls out.
FAQs: Your Top Questions About Tooth Fillings Answered
Front teeth usually benefit from tooth-coloured composite or ceramic fillings for a natural appearance. Back teeth require strength, so amalgam, gold, or high-strength composite may be recommended.
Composite (white) fillings are durable and suitable for most teeth, but metal (amalgam or gold) fillings may last longer in high-pressure areas such as back molars.
Amalgam and gold fillings often last over a decade; composite and glass ionomer fillings may need replacement within 5 – 7 years. Ceramic fillings are also very durable. Lifespan depends on placement, bite forces, and oral hygiene.
Look out for sensitivity, pain when biting, visible cracks or gaps, roughness, or food getting trapped. If you notice these, book a dental review.
Most patients experience little discomfort due to local anaesthetic. The Wand system can reduce injection discomfort, but individual experiences vary.
Wait until numbness has fully worn off before eating. After that, avoid very hard or sticky foods for a day or two.
If decay or damage is extensive, your dentist may recommend a crown, onlay, or root canal treatment instead of a standard filling.
Innovations include CEREC technology for single-visit crowns, bioactive materials, and computer-controlled local anaesthesia using The Wand.
Maintain good oral hygiene, limit sugary foods, and attend regular dental check-ups for early detection and advice.
Amalgam is considered safe for most adults and is strictly regulated in the UK. Its use is restricted for deciduous (baby) teeth, children under 15, and pregnant or breastfeeding patients, except where strictly necessary for the patient’s specific medical needs. Your dentist will discuss suitable options for you.
When to See a Dentist About Tooth Fillings
Recognising the early signs of tooth decay or a damaged filling can help prevent further dental problems. Consider booking a dental appointment if you experience any of the following symptoms:
- Tooth sensitivity: Discomfort when consuming hot, cold, or sweet foods and drinks.
- Toothache or pain when chewing: Persistent discomfort that may indicate decay or damage.
- Visible tooth damage: Cracks, holes, or dark spots on your teeth.
- Food getting trapped: Food frequently becoming stuck between teeth or around existing fillings.
- Damaged or loose fillings: Fillings that feel rough, cracked, loose, or have changed in appearance.
Regular dental check-ups can also help identify potential problems before noticeable symptoms develop.
When to Seek Urgent Dental Care
If you experience severe or persistent toothache, facial swelling, fever, or signs of a dental infection, seek an urgent dental assessment. Early diagnosis and appropriate treatment can help reduce the risk of further complications.
Medical Emergency: If you experience difficulty breathing or swallowing, rapidly worsening swelling affecting your breathing, uncontrolled heavy bleeding from the mouth, or a serious facial or jaw injury, call 999 or seek immediate emergency medical attention.
