Treating Cavities in Children

What are cavities? Dental cavities, also referred to as caries, are holes in teeth caused by bacteria along with certain kinds of foods high in sugar or starch. Bacteria eats away the enamel and structure of teeth. Bacteria also erodes away gum tissue causing periodontal disease. As bacteria eats away your tooth, this is known as tooth decay and cavities form.

Located in Dover, Dr. Patrick Wilson can help tooth decay prevention efforts for you children. If a cavity is found we will recommend the procedure specific to your child's case. In many cases a simple filling will prevent further decay and relieve the pain. If the case is more serious Dr. Wilson may recommend other procedures.

There are hundreds of different types of bacteria that are normally present in the mouth. Some bacteria combines with the foods you eat. As bacteria combines with food and saliva, it forms a sticky substance called plaque. Foods rich in sugar and starches add to the stickiness of the plaque. Plaque only takes 20 minutes to form after eating. The longer the plaque remains on your teeth the harder it is to remove. If plaque remains on your teeth for more than a couple of days it turns into tartar or calculus. The bacteria in the plaque will convert sugar into acid that dissolves the tooth structure causing holes, or cavities. This is how a cavity is formed. Cavities can cause a fair amount of pain or sensitivity as the "hole" gets closer to the tooth root.

The parts of teeth that are most vulnerable to tooth decay are areas where plaque can accumulate easily. Plaque tends to settle into the pits and pockets of your teeth or on top of your teeth. Plaque also likes to hide in-between your teeth and next to the gum line. A cavity starts to erode the outer layer of the tooth known as the enamel. As the cavity gets deeper and deeper it penetrates into the softer inner layer of the tooth known as the dentin. When the cavity reaches dentin you will notice pain and discomfort.

Everyone who eats is at risk of tooth decay. As soon as your child's first tooth appears, they are at risk for tooth decay. Although saliva helps prevent plaque from attaching to teeth and helps wash away and digest food particles, additional cleaning must be present to ensure tooth decay prevention. Genetic factors may affect your child's risk of tooth decay. Your child may be at a higher risk of developing tooth decay if they have a low salivary flow or dry mouth. Tooth size and shape, thickness of enamel, tooth position, tooth eruption time and sequence, and your child's bite all may contribute to a higher risk of tooth decay. Only Dr. Wilson can help determine the correct routine and care for your child's teeth.

Silver Diamine Fluoride, often referred to as SDF, is a minimally invasive treatment used to help stop the progression of cavities, especially in younger children or those who may not yet tolerate traditional dental procedures.

SDF is typically recommended when:

  • Cavities are in the early stages
  • A child is very young or anxious
  • Treatment needs to be quick and non invasive
  • We want to delay or avoid more extensive procedures

This treatment is applied directly to the affected area and works by stopping the decay from progressing. It does not require drilling, making it a comfortable option for many children receiving children’s dental care in New Hampshire.

It is important for parents to know that SDF may darken the treated area, which is a normal and expected part of the process. Our kids dentist team will review whether this option is appropriate based on the location of the cavity and your child’s needs.

When cavities are more developed, a traditional filling may be the best option to restore the tooth. Tooth colored fillings remove the decayed portion of the tooth and replace it with a durable, natural looking material.

Fillings are typically recommended when:

  • The cavity has progressed beyond early stages
  • There is structural damage to the tooth
  • A long term restoration is needed

As a trusted pediatric dentist in New Hampshire, Dr. Wilson uses gentle techniques to ensure your child remains comfortable during treatment while restoring the tooth’s function and appearance.

We had an absolutely wonderful experience. After going someone where else first that just wanted to pull teeth instead of fixing them we tried here. All the staff and doctor were absolutely wonderful. Came up with a wonderful care plan, my daughter had zero pain or discomfort and he addressed a few issues at once. We fee very comfortable with staff knowledge, explanation and care given. The self pay membership plan was also a huge cost savings as well as we self pay regardless.

Hands down the best experience my 2 year old and I have had yet! It was a breeze talking with Kris to schedule my son’s first dentist appointment. She was so nice and very helpful when I asked her about insurance coverage. She had Gabby in billing call me to answer a couple questions I had.

I was so nervous about my son’s first dentist appointment. He is a VERY active boy who rarely ever sits still.

When we arrived at GOPD, we liked how clean and orderly the general atmosphere was. The front desk staff were so down to earth and nice, it made me feel a lot better. We then met with dental hygienist, Sky, and she was so unbelievably sweet, patient and helpful with my son, showing him all the tools and letting him try them out. Dr. Patrick was amazing as well!

Honestly, I don’t have one bad thing to say. Everyone was so welcoming, nice and knowledgeable! My husband and I were impressed and very grateful to have found such a great place!

It was such a great first experience! Highly recommend!
