What Causes Tooth Decay?
Tooth decay happens when plaque — a sticky film of bacteria — builds up on your teeth and produces acids that wear away enamel over time. Left untreated, this can create a cavity, a small hole in the tooth that gradually grows deeper. Sugary and starchy foods, infrequent brushing, and skipping regular cleanings all make decay more likely. Because early decay often doesn't hurt, it's usually caught during a routine checkup rather than because of a symptom you'd notice at home.
Signs to Watch For
Early cavities frequently show no symptoms at all, which is part of why we check for them at every cleaning. As decay progresses, you may notice sensitivity to sweets or temperature, a visible dark spot or pit on the tooth, or mild discomfort when chewing. Pain that's sharp, constant, or wakes you up at night usually means decay has reached deeper into the tooth and needs prompt attention rather than waiting for your next scheduled visit.
How We Treat It
Treatment depends on how far decay has progressed. Early cavities are typically treated with a simple, tooth-colored filling in a single visit. Left longer, decay that reaches the inner pulp of the tooth may require a root canal to save it. We always aim to treat conservatively and preserve as much of your natural tooth structure as possible — catching decay early is what makes that possible.
