What Is a Tooth Filling?
Dental fillings, including materials like composite resin and glass ionomer, are special types of materials used to repair a tooth after it has suffered some sort of damage, such as:
- Tooth decay
- Root canals
- Dental cracks
- Dental chips
- Tooth fractures, etc.
In these cases, the structure of the tooth is often compromised. For example, with tooth decay, your dentist will need to remove the infected tissue—leaving behind a cavity that must be filled. This is where dental fillings come in: they restore the strength of your natural tooth and prevent bacteria and unwanted food particles from getting inside the tooth’s pulp.
What are the different dental filling material options?
There are several dental filling materials used worldwide, each offering different benefits depending on the condition of your tooth and your personal preferences:
-
Composite resin
-
Glass ionomer cement
-
Gold fillings
-
Porcelain fillings
-
Dental amalgam
Your dentist will help you decide on the most suitable material based on your oral health needs, budget, and aesthetic concerns.
Tooth filling process
When you visit your dentist to get a filling, the first thing they’ll do is inspect the tooth to establish your treatment. In some cases, you may even need a dental X-ray to determine the full extent of the damage and if a filling is enough to restore the tooth structure. For severely damaged teeth, you may require alternatives such as dental crowns or even implants. If you do need a filling, the process itself is very straightforward:
- Examination – Your dentist will assess the tooth to confirm if a filling is appropriate. Sometimes an X-ray is needed to see the full extent of the damage.
- Anaesthesia – The area is numbed to ensure comfort throughout the procedure.
- Decay removal – If a cavity is present, the decayed tissue is removed carefully.
- Filling and shaping – The cavity is then filled with a suitable material (like composite resin or glass ionomer) and shaped to fit your tooth. A special light may be used to harden the material.
- Finishing touches – The filling is polished, and your bite is checked for proper alignment.
Understanding and Addressing Tooth Pain After a Filling
It’s perfectly normal to feel a bit of sensitivity after getting a filling—especially when you’re having something hot or cold. This can happen if the nerve inside your tooth is a little irritated or if the filling slightly changes the way your teeth come together when you bite. If you have sensitive teeth, materials like composite resin or glass ionomer are often a gentler choice compared to traditional amalgam.
That said, if your tooth is still feeling sore or sensitive weeks or even months later, it might mean the filling needs a small adjustment—or there could be something else going on beneath the surface. Keeping up with good brushing and flossing habits and seeing your dentist for regular check-ups can help catch any issues early before they turn into bigger problems.

FAQs
How long does a tooth filling last?
The lifespan of a filling depends on the material used and how well you care for your teeth. On average, composite (tooth-coloured) fillings last around 5–7 years, while amalgam (silver) fillings can last 10–15 years or more. Regular dental check-ups help ensure your fillings remain in good condition.
Can you fill a damaged tooth?
Yes, in many cases a damaged tooth can be restored with a filling, especially if the damage is caused by decay or a small chip. If the tooth has more significant damage or structural loss, your dentist may recommend a crown, inlay, onlay, or other restorative treatment to provide longer-lasting protection.
How many fillings are normal?
There’s no set “normal” number of fillings. Some people may have none, while others may need several throughout their lifetime depending on their diet, oral hygiene, and susceptibility to tooth decay. The important thing is to have any decay treated promptly to prevent further damage.
Will tooth filling damage the teeth?
No, fillings are designed to protect and strengthen your teeth. To place a filling, your dentist removes the decayed portion of the tooth and replaces it with a durable material. This helps stop further decay and restores the tooth’s natural function.
