A dental filling repairs a tooth affected by decay or minor damage, restoring its structure and function and preventing further deterioration or infection. Tooth-coloured composite material is placed after the damaged tissue is removed. The need for a filling is confirmed through dental examination rather than symptoms alone.
What to Expect
- Tooth-coloured composite fillings only. No metal, no silver.
- Treatment is usually completed in one visit.
- Local numbing is used when needed, with comfort monitored throughout.
- Typical cost $238 to $490 per tooth. Final pricing varies based on your individual clinical needs.
- Typical lifespan 1 to 12 years, depending on bite forces and oral habits.
- Fillings are monitored at your regular dental visits rather than forgotten about.
The need for a dental filling is confirmed by examination rather than by symptoms, so the first step is an assessment rather than an appointment for treatment. Where one is needed, it is usually completed in the same visit, and the cost is explained before it starts.
When Is a Dental Filling Needed?
When decay or a small fracture has taken structure out of the tooth. A dental filling is recommended in these situations:
- Cavities detected on examination
- Small fractures in the tooth surface, where filling teeth early prevents the crack spreading
- Where structure and function need restoring
- To prevent further damage or infection spreading
Why It Is Found Before It Hurts
The need is confirmed through a dental exam, not from how the tooth feels. Decay between teeth is often invisible and painless until it is well established, which is why X-rays at recall matter more than most patients realise.

What Are Composite Fillings Made Of?
Tooth-coloured composite resin, and that is the only material used here. Composite fillings are bonded into the prepared cavity rather than wedged into it.
- Material choice is discussed based on location and function
- Aesthetic and durability considerations are explained to you
- Recommendations are tailored to each individual case
Tooth coloured fillings are the standard for a straightforward reason. A filling in a front tooth has to disappear, and one in a molar has to withstand chewing load.
Both are achievable in composite, but the emphasis differs. White fillings front teeth cases are planned around appearance, while back teeth are planned around force. That is the whole of the teeth filling material decision here, since composite is the only option offered.
Does Getting a Filling Hurt?
Local numbing is used when needed, and the procedure is performed with your comfort actively monitored rather than assumed.
The teeth filling procedure is short and usually done in a single appointment:
- The tooth is examined and the extent of the decay confirmed.
- Local numbing is used where it is needed.
- The damaged tissue is removed and the cavity prepared.
- Composite is placed, shaped and bonded.
- Aftercare instructions are provided before you leave.
Sensitivity Afterwards
Afterwards, some sensitivity is normal. Teeth sensitive after filling placement is discussed with you in advance, so you know what falls inside the expected range rather than worrying about it.
How Long Do Fillings Last?
Typically 1 to 12 years. That range is genuinely wide because the two biggest factors are your bite forces and your oral habits, not the material.
- Lifespan depends on bite forces and oral habits
- Regular dental visits help monitor fillings over time
- Replacement is recommended if wear or leakage occurs
- Longevity is discussed with you during treatment planning
What Shortens a Filling's Life
If you grind, that shortens filling life considerably, and an occlusal night guard is worth discussing before a filling fails rather than after. According to the Canadian Dental Association, regular check-ups allow existing restorations to be monitored alongside your natural teeth.
How Much Does a Dental Filling Cost?
Typical cost is $238 to $490 per tooth. Final pricing varies based on your individual clinical needs.
- Cost varies by material and tooth location
- Insurance coverage is reviewed when applicable
- You are informed of costs before treatment
- Basic fillings are covered under the Canadian Dental Care Plan, subject to CDCP approval and limits
The teeth filling cost conversation is really a conversation about timing. The preventive value of treating decay early is that a filling now costs a fraction of a root canal later, which is the honest argument for not waiting.
