The most common signs of a cavity are sensitivity to sweets, hot, or cold; a toothache or pain when you bite; a visible hole or pit; and white, brown, or black spots on a tooth. Food that keeps catching in the same spot can be another clue.
The catch is that early cavities usually don’t cause any symptoms. By the time a tooth starts to hurt, decay has often moved deeper.
That’s why regular exams at The Dentist in Glendale, AZ, matter so much, especially in candy-heavy months like October.

How Does a Cavity Form?
Cavities don’t appear overnight. As the National Institute of Dental and Craniofacial Research explains, decay begins when bacteria in your mouth turn sugars into acids that attack the tooth’s outer layer (enamel).
At first, the enamel loses minerals and may show a chalky white spot. Over time, that weak spot breaks down and becomes a hole, which is the cavity itself.
What Are the Early Signs of a Cavity?
Early decay is easy to miss. Look for:
- White, chalky spots on the tooth surface, a sign of mineral loss
- Brown or black spots or staining that doesn’t brush away
- Mild sensitivity to sweets in one area
- Food that catches between the same teeth, or floss that shreds in one spot
Many early cavities cause no discomfort at all. A close look and X-rays during a routine dental exam are often the only way to find them.
What Are the Signs of a Deeper Cavity?
As decay moves through the enamel toward the inner layers of the tooth, symptoms usually become harder to ignore:
- Sensitivity to hot or cold that lingers after you eat or drink
- A toothache that comes on by itself, sometimes at night
- Pain when you bite down
- A hole or pit you can see or feel with your tongue
- Swelling, a bad taste, or a pimple-like bump on the gum near the tooth
Swelling or a bump on the gum can mean an infection. If you notice either, call us promptly rather than waiting for your next checkup.
Does Halloween Candy Really Cause Cavities?
Candy alone doesn’t cause cavities. What matters most is how often sugar touches your teeth and how long it stays there.
Some treats are harder on teeth than others:
- Sticky candy like caramels, taffy, and gummies clings to teeth and grooves.
- Hard candy and lollipops bathe teeth in sugar for a long time.
- Sour candy is both sugary and acidic, a tough combination for enamel.
- Plain chocolate tends to rinse away more easily.
A few habits help your family enjoy the season without the aftermath:
- Eat treats with a meal or in one sitting instead of grazing all day.
- Drink water afterward to rinse away sugar.
- Brush twice a day with fluoride toothpaste and clean between teeth daily.
In Arizona’s dry climate, staying hydrated helps, too. Saliva is one of your teeth’s natural defenses, and a dry mouth gives bacteria more of an advantage.
How Are Cavities Treated?
Treatment depends on how far the decay has gone:
- Very early decay: Before a hole forms, fluoride and better home care can sometimes stop the process.
- Small to moderate cavities: A tooth-colored filling is the most common fix. We numb the tooth, remove the decay, and fill the space with a material matched to your natural tooth shade.
- Large cavities: When too much tooth is lost, a crown may be needed to protect what’s left.
- Decay that reaches the nerve: A root canal may be needed to save the tooth.
The earlier a cavity is found, the simpler the repair usually is. If dental visits make you or your child nervous, nitrous oxide and oral conscious sedation are available at our office.
Frequently Asked Questions
Can a cavity go away on its own?
No. Once a hole has formed in the enamel, it can’t heal on its own and needs to be repaired, usually with a filling. Very early decay, before a cavity forms, can sometimes be stopped with fluoride and good home care.
How long does a filling take?
Most fillings can be done in a single visit. The time depends on the size and location of the cavity and how many teeth are being treated. We’ll let you know what to expect before we begin.
Do kids get cavities in baby teeth?
Yes. Baby teeth have thinner enamel than adult teeth, so decay can spread quickly. Cavities in baby teeth should still be treated, since these teeth hold space for adult teeth and an infection can be painful. Ask us about sealants for extra protection on back teeth.
