When part of your tooth gets damaged by decay – also known as a cavity – it’s not something you can fix just by brushing. If the cavity is left untreated, it can grow and sink deeper into the tooth, eventually reaching the nerve.

This can often lead to pain and much bigger problems, like needing a root canal or even losing a tooth. A filling is a simple, but very effective way to repair the damage. The dentist removes the decayed or damaged portion of the tooth, then fills the gap with a safe filling material to restore the shape and strength of your tooth – helping you to bite, chew and smile normally again.

What happens during a filling appointment?

First, the dentist will numb the area around the tooth so you don’t feel any pain. Next, the decayed or damaged enamel is carefully cleaned away, which sometimes involves a drill and a bit of smoothing.

Next, the dentist will fill the cavity with a filling material. Many people choose a tooth-coloured, or composite filling that blends with their natural tooth colour. Finally, the filling is smoothed and polished so your bite feels natural when you eat and talk.

Usually, the whole process takes 30-60 minutes and you can go back to normal activities soon after.

Do I need to get a filling urgently?

It’s often worth getting onto fillings early on. When you ignore a cavity, the decay will only get worse. What might begin as a small hole can spread deeper, damage more of the tooth, hit the nerve and lead to a serious problems – pain, infection or even loosing the tooth.

A filling stops the damage from growing. It preserves your natural tooth structure, resolves the tooth’s strength and keeps it functioning properly.

Plus, modern fillings – especially tooth-coloured ones – make the repair nice and discreet.

What should I ask when I get a filling?

It’s completely normal to have questions before getting a filling; our dentists will always be happy to walk you through the details. Here are a few helpful things you might want to ask, so you know exactly what’s happening and why.

What type of filling material do you recommend?

There are a few options: tooth-coloured composite, amalgam (silver), or sometimes other specialised materials. Each has pros and cons depending on the tooth, size of the cavity and your budget. Asking this helps you to understand what will look best, last longest and suit your situation.

How big is the cavity?

This gives you an idea of how much of the tooth needs repairing. A small cavity is quick and straight forward to repair, while a larger one may need more care. It also helps you to understand why the filling is needed now, rather than later.

Will the filling match my tooth colour?

If you’re getting a tooth-coloured filling, you can check how well it will blend with your natural tooth. Many people like to know their repair will be almost invisible.

How long will the filling last? 

All fillings wear down eventually, but different materials will last for different lengths of time. This helps to plan future check-ups and understand how to care for your fillings.

Is there anything I should avoid afterward?

Our dentist team will be able to tell you whether you need to avoid hot drinks, chewing on that side or very hard foods for a short period of time. This will help your tooth to settle properly.

What are my alternatives?

Sometimes there are other options like fluoride treatments (for very early decay), inlays/onlays, or even crowns for major damage. It’s always good to know the range of choices before you commit – and our dentists will be happy to chat about them.

How much will it cost, and is it covered by insurance?

Dental costs can vary depending on the size, material and position of the fillings. Asking upfront saves surprises later and helps you feel more in control.

What should I know after getting a filling?

First, your tooth might be a little sensitive to hot, cold or chewing for a few days. This is normal, the tooth is just settling.

Also, fillings don’t last forever. Depending on the material and how well you care for them, they’ll do the job for several years – but you might need a replacement eventually.

Take good care of your teeth. Brush them twice a day, floss daily, avoid biting on hard things like ice or hard nuts and keep regular dental check-ups. All of these things help your fillings to last longer and keep you smiling bright!
