Restorative Fillings
Short answer: A filling repairs a tooth damaged by decay or fracture, restoring its strength and shape. Modern tooth-coloured fillings are matched to your natural shade, so repairs at the front of the mouth are effectively invisible. Treating decay early keeps the work small — untreated, it progresses to root canal treatment or extraction.
Decay does not reverse itself once it has broken through the enamel. The good news is that a cavity caught early is a short, straightforward appointment. The same cavity left for a year is a considerably bigger and more expensive problem.
How to tell you might need one
Cavities frequently cause no symptoms at all until they are quite advanced, which is exactly why check-ups and X-rays matter. When there are signs, they tend to be:
- Sensitivity to sweet, hot or cold that lingers afterwards
- A visible dark spot, hole or chalky white patch
- Food consistently catching in one particular spot
- A rough edge you keep finding with your tongue
- Ache when biting down on one tooth
Pain that keeps you awake at night generally means the decay has reached the nerve, and needs to be looked at promptly — see emergency care.
What the appointment involves
A straightforward filling is usually a single visit:
- The area is numbed so the procedure is comfortable
- The decayed tissue is removed completely — leaving any behind means it continues under the filling
- The cavity is cleaned and prepared
- Tooth-coloured composite is placed in layers and hardened with a curing light
- The filling is shaped and polished, and your bite is checked so it feels natural
You can eat normally once the numbness wears off, though some people notice mild sensitivity for a few days.
Preventing the next one
Fillings repair damage; they do not stop the process that caused it. What actually reduces new cavities:
- How often you eat sugar matters more than how much — every exposure restarts an acid attack lasting around 20 minutes. Constant snacking and sipping sweet drinks is far worse than the same sugar eaten at once.
- Clean between the teeth daily — that is where a large share of cavities start.
- Use fluoride toothpaste, and spit rather than rinsing afterwards so it keeps working.
- Keep up regular check-ups so new decay is caught while it is still small.
What a filling costs — and whether filling beats pulling
A filling is not on our published price list, because the cost genuinely varies with how much tooth has been lost, which surface it is on, and how many teeth are involved. The examination that tells you starts at TT$280, and you get an itemised quotation before anything begins.
What moves the figure: how much of the tooth is left (the big one), which tooth, and whether decay has reached the nerve — because past that point it is root canal treatment rather than a filling.
Is it cheaper to fill a cavity or pull the tooth?
Pulling is cheaper on the day. It is usually more expensive within a few years, and that is not a sales line — it is what happens to the gap. Neighbouring teeth drift, the opposing tooth over-erupts, and replacing what was removed costs several times what the filling would have. What actually happens if you leave a gap.
Extraction is the right answer sometimes, and we will say so. But "just pull it" as a way to save money usually is not saving money.
Can a rotten tooth be filled?
It depends how far it has gone. If enough sound tooth remains to hold a filling, yes. If the decay has undermined the walls, the tooth needs a crown to hold it together; if it has reached the nerve, a root canal first. A tooth that is broken down to the gum and infected may genuinely be beyond keeping — an x-ray answers it in minutes rather than by guesswork.
Common questions
How much does a dental filling cost in Trinidad?
It varies with how much tooth has been lost, which surface is affected and how many teeth are involved, so we quote after an examination rather than publishing a figure. The examination itself starts at TT$280 and you receive an itemised quotation before treatment begins.
Is it cheaper to fill a cavity or pull the tooth?
Pulling is cheaper on the day and usually more expensive within a few years, because the gap causes neighbouring teeth to drift and the opposing tooth to over-erupt, and replacing the tooth costs several times the filling. Extraction is sometimes the right answer, and we will tell you when it is.
Can you fill a rotten tooth?
If enough sound tooth remains to hold a filling, yes. If decay has undermined the walls the tooth needs a crown; if it has reached the nerve, root canal treatment first. An x-ray answers it in minutes.
Do fillings hurt?
The tooth is numbed first, so the procedure itself should not hurt. You may feel pressure and vibration. Mild sensitivity for a few days afterwards is normal; sharp or worsening pain is not, and you should contact us.
How long do fillings last?
Well-placed composite fillings often last many years, though this depends on size, position, your bite and your oral hygiene. They are checked at every routine visit and replaced when they show wear or leakage.
Are tooth-coloured fillings as strong as metal ones?
For most everyday cavities, modern composite is more than strong enough and bonds to the tooth structure, which allows a more conservative preparation. For very large cavities in back teeth we will discuss which option gives the best long-term result for that specific tooth.
Can a cavity heal on its own?
Very early enamel demineralisation — a chalky white spot before any hole forms — can sometimes remineralise with fluoride and better cleaning. Once decay has broken through the enamel surface, it cannot heal and needs a filling.
