A cavity doesn’t show up overnight. It’s the end result of a slow process, which is actually good news, because it means there’s plenty of time to catch it early, when fixing it is quick, comfortable, and a lot less expensive.
The four stages of a cavity
Here’s roughly how it plays out:
- Plaque builds up. A sticky film of bacteria forms on your teeth, fed mostly by sugars and starches. Left alone, it hardens into tartar that brushing can’t remove.
- Enamel wears down. Acids from that plaque slowly soften and erode the outer layer of your tooth. At this stage you usually feel nothing at all.
- Decay reaches the dentin. Once acid breaks through the enamel, it hits the softer layer underneath. This is when sensitivity to hot, cold, or sweets often starts.
- It reaches the nerve. Now you’re in real toothache territory, and possible root canal territory too. Nobody wants to be here.
Early signs worth paying attention to
The tricky thing about cavities is that the earliest stage is painless. By the time a tooth really hurts, decay has usually been at work for a while. Watch for a twinge with cold drinks or sweets, a tooth that catches food more than it used to, visible dark spots or white chalky patches, or breath that stays stale no matter how much you brush.
And if you have none of those symptoms? That’s exactly what regular checkups are for. We can spot decay long before you’d ever feel it.
If you do have a cavity, here’s the good news
Caught early, a cavity is a quick fix. A tooth-coloured filling blends right in, and most appointments are done within the hour. If it’s been a while since your last visit and you’re bracing for a lecture, don’t. We’re just glad you’re here, and if nerves are part of what kept you away, we have sedation options and Netflix in the chair.
Frequently asked questions
Can a cavity heal on its own?
In the very earliest stage, before a hole forms, enamel can re-mineralize with good brushing, fluoride, and diet changes. Once there’s an actual cavity, it needs a filling. It won’t reverse, and waiting only lets it grow.
Do kids get cavities more easily?
Baby teeth have thinner enamel, so decay can move faster. That’s why we like seeing kids early and often, starting with free Happy Visits for little ones under three.
How can I prevent cavities?
Brush twice a day with fluoride toothpaste, clean between your teeth daily, go easy on constant snacking and sugary drinks, and keep up with regular exams and cleanings. Simple, boring, and very effective.
