Toothpaste ads Norman Rockwell painted in the 1950s featured happy children with big smiles and the slogan “Look, Mom—no cavities!” But while cavities are more common in children and adolescents, tooth decay can affect people of all ages.
Do you know how to tell if you have cavities?
About 92% of adults who have teeth also have tooth decay (dental caries). Slightly more than a quarter (26%) have untreated cavities. Worldwide, dental caries is the most common noncommunicable disease.
At Penn Dental Family Practice (PDFP), we inform children and adult patients how to know if they have a cavity. The following will teach you signs you may have a cavity, how to get a cavity treated if you do, and how to help prevent future ones.
What Are Dental Cavities and What Causes Them?
Dental cavities are small holes in your teeth’s enamel (the tooth’s hard, outer layer). Cavities form when bacteria, acid, food particles, and saliva combine to form the sticky film called plaque. Acids in plaque cause cavities.
Plaque begins accumulating on teeth in as short a time as 20 minutes after eating. When not removed by proper brushing and flossing, plaque hardens into tartar (calculus), which only dentists can scrape away.
How Can You Tell if You Have Cavities?
PDFP patients sometimes ask, “How do I check myself for cavities?”
Sensitivity to hot and cold food and drink may indicate you have a cavity. So may a bad toothache you can’t shake.
You should also be aware of other potential signs of a cavity, including:
- Chronic bad breath or a persistent bad taste in your mouth.
- Pain in the mouth that comes and goes.
- Pain that varies from mild to sharp, especially when eating or drinking something sweet.
- Pain that worsens when you bite or chew.
- Yellowish-brown stains on the tooth’s surface, revealing layers under the enamel.
- Visible holes or pits in the teeth.
Contrary to popular assumptions, cavities don’t always cause pain, especially in early stages. You can’t feel small cavities with your tongue, and cavities aren’t always visible to the naked eye.
To tell if you have cavities, schedule regular visits to your dentist.
What Happens If You Ignore Cavities?
Cavities are permanent damage to your enamel. Ignoring them won’t make them go away.
In an untreated cavity, bacteria can migrate from the enamel to the dentin beneath (hard, mineralized tissue), eventually reaching the pulp (the nerves and blood vessels at a tooth’s center). The growing cavity can lead to severe toothache, serious inflection, and tooth loss.
The sooner a cavity is detected and treated, the less likely it is to cause bigger problems.
How Do Dental Professionals Find and Treat Cavities?
Dental hygienists and dentists know what cavities look like, and will be alert for them when cleaning and examining your teeth. Since cavities aren’t always visible, your dentist will probe for soft areas which may indicate tooth decay. Dentists also use X-rays to find cavities.
If your dentist discovers you have a cavity, treatment options depend on its severity.
- Early stages: Fillings and crowns
Treating a cavity before the pulp has become infected generally involves a filling, with or without a crown.
Once your dentist removes the tooth’s infected and damaged area, the area is “filled” with porcelain or tooth-colored composite resin.
To prevent further decay and damage, the dentist places a custom-fit crown over the tooth’s entire surface. Crowns can be made of gold or another metal, porcelain, or a combination.
- Later stages: Root canal treatment or extraction
If the pulp is infected, your dentist will likely need to perform a root canal procedure to save the tooth. This treatment involves removing the infected tissues in the pulp and cleaning out the canals to prevent future infection.
If the infection has progressed too far and the tooth can’t be saved, your dentist will extract it to prevent further damage to your oral and overall health. You may then need prosthodontic treatment to preserve your bite’s integrity and restore your smile.
What Can You Do to Reduce Your Risk of Cavities?
The American Dental Association recommends brushing your teeth twice a day—for two minutes each time, with fluoride toothpaste—and cleaning between teeth with floss or another safe interdental cleaner at least once a day.
Eating a diet low in sugary, sweet foods and drinks also promotes healthy teeth. These foods support good oral health:
- Dairy Products
Milk, yogurt, and cheese contain calcium and phosphates that help rebuild and reinforce tooth enamel.
- Fiber-rich Fruits and Vegetables
Many fruits and vegetables are packed with fiber that promotes saliva production and combats enamel-damaging acids. Good choices include raspberries, unpeeled apples, pears, bananas, green peas, broccoli, brussels sprouts, and turnip greens.
- Foods Containing Fluoride
Several toothpastes include fluoride. Many commercially prepared foods also naturally contain this mineral. Fluoride-rich foods can include poultry, seafood, powdered cereals, and dehydrated soups. Also, drinking more fluoridated water, “the best beverage for maintaining your oral health,” opposed to sugary cola will help promote good oral hygiene.
