Cavities — also known as tooth decay or dental caries — are one of the most common dental problems seen at Tridont Dental. Despite being highly preventable, millions of people develop cavities each year. Left untreated, they can lead to pain, infection, and even tooth loss.
In this post, we’re breaking down everything you need to know about cavities: what causes them, how to spot them early, and — most importantly — how to prevent them.
What Are Cavities?
A cavity is a permanently damaged area in the hard surface of your tooth that develops into tiny holes or openings. Cavities form when plaque, a sticky film of bacteria, builds up on your teeth and produces acids that eat away at the enamel.
There are three main types of cavities:
- Smooth surface cavities – form on the flat surfaces of teeth.
- Pit and fissure cavities – develop in the grooves of the chewing surfaces.
- Root cavities – occur on the surface of the tooth roots, usually when gums have receded.
What Causes Cavities?
Cavities don’t happen overnight. They’re the result of a combination of factors that contribute to the breakdown of tooth enamel. The most common causes include:
- Poor Oral Hygiene
Not brushing and flossing properly allows plaque to accumulate and harden into tartar, which harbors bacteria that produce acid.
- Frequent Snacking or Sugary Drinks
Eating sugary or acidic foods and drinks throughout the day fuels bacteria in your mouth, increasing acid production that erodes enamel.
- Lack of Fluoride
Fluoride helps remineralize and strengthen teeth. Without enough of it (in water or toothpaste), your teeth are more prone to decay.
- Dry Mouth
Saliva helps wash away food particles and neutralize acids. A dry mouth, caused by medications or medical conditions, increases your risk of cavities.
- Worn Dental Fillings or Crowns
Over time, dental restorations can break down and allow bacteria to sneak underneath, causing decay.
Common Symptoms of Cavities
Cavities often develop silently, especially in the early stages. That’s why regular dental checkups are so important. However, as cavities progress, you might notice symptoms such as:
- Toothache or spontaneous pain
- Sensitivity to hot, cold, or sweet foods and drinks
- Visible holes or pits in your teeth
- Brown, black, or white staining on the surface of a tooth
- Pain when biting or chewing
If you’re experiencing any of these symptoms, don’t wait. The sooner we catch and treat a cavity at Tridont Dental, the less invasive the treatment will be.
How Are Cavities Treated?
Treatment depends on the severity of the cavity. Common options include:
- Fluoride Treatments – For early-stage cavities, fluoride can help restore your enamel.
- Dental Fillings – The most common treatment; decayed material is removed and replaced with a filling material like composite resin.
- Crowns – If a cavity is large, a crown may be needed to cover and protect the remaining tooth structure.
- Root Canal Therapy – If decay reaches the inner pulp of the tooth, a root canal may be necessary to remove infected tissue and save the tooth.
- Tooth Extraction – In severe cases, if the tooth is beyond repair, it may need to be removed.
How to Prevent Cavities
Prevention is always better than cure — and cavities are no exception. Here are our top tips for cavity prevention:
- Brush and Floss Daily
Brush your teeth twice a day with fluoride toothpaste and floss once a day to remove food and plaque between teeth.
- Limit Sugary Snacks and Drinks
Reduce your intake of sugary treats, sodas, and juices. If you do indulge, rinse with water or brush your teeth afterward.
- Stay Hydrated
Drinking plenty of water — especially fluoridated water — helps keep your mouth clean and supports saliva production.
- Use Dental Products with Fluoride
Fluoride strengthens enamel and makes teeth more resistant to decay. Choose toothpaste and mouthwash that contain fluoride.
- Regular Dental Checkups
Visit Tridont Dental every 6 months for cleanings and checkups. We can spot early signs of decay and help you stay on track with your oral health.
- Consider Dental Sealants
Sealants are thin coatings applied to the chewing surfaces of back teeth, where cavities are most likely to form. They’re especially helpful for kids, but adults can benefit too!
