Causes and Risk Factors
A cavity is a small hole in your tooth that occurs when the hard outer layer of the tooth, called theenamel, is damaged. Cavities form when bacteria and sugar in the mouth create an acid that eats away at the enamel. Because bacteria are naturally present in the mouth, anyone can get a cavity.

Signs and Symptoms
Cavities can be tricky to catch, since there aren’t always noticeable symptoms that show up during the early stages of tooth decay. As the cavity continues to form, watch out for the following signs in your child:
When to Seek Medical AttentionCall a dentist or other healthcare provider right away if your child is experiencing fever, swelling, or pain. It could mean there’s anabscess(pocket of pus around the root of the tooth) that can lead to a severe tooth infection and potential hospitalization, if ignored.

Treatment options include:
Many people of all ages have anxiety or fear about going to the dentist. Rest assured, dentists uselocal anesthesiato numb the area before performing common cavity treatments, andgeneral anesthesiafor procedures like tooth extraction, so your child should not feel any pain.
If you think your child may need additional support to ease their mind or pain level while undergoing cavity treatment options, check with your dentist’s office about options to help them relax. Pediatric dentists are used to working in a completely kid-focused and friendly environment, and they may be able to help deal with dental anxiety.

A Word From Verywell
Oral health is important for your child’s overall health and well-being. That said, dentists don’t expect children to be perfect. Cavities are extremely common, and most of us will get at least one in our lifetime. The American Academy of Pediatrics recommends “everything in moderation,” so you should feel free to give your child occasional candy or special treats, just as long as they’re brushing, flossing, using fluoride, getting routine dental care, and eating a healthy diet.
Cavities left untreated are painful for your child and can have a negative impact on their overall health. Not to mention, untreated cavities can cause more cavities as the infection spreads. It’s best to seek dental treatment as soon as possible and accessible to avoid any unintended consequence.
