Tooth Infections in Children

Tooth infections occur when bacteria or foreign substances enter the tooth and reach the pulp or root. Cavities, as well as broken or cracked teeth, can create a direct pathway for bacteria to penetrate deep into the tooth. Once this happens, an infection may develop, often causing significant discomfort or pain.

At Great Outdoors Pediatric Dentistry, we provide prompt and effective children’s dental care in New Hampshire to diagnose and treat infections early. Visiting a pediatric dentist in New Hampshire at the first sign of discomfort can help prevent complications and protect your child’s oral health.

Kids Dental Infection Symptoms

Common signs of a tooth infection may include:

  • Toothache
  • Severe or continuous pain
  • Gnawing or throbbing discomfort
  • Sharp or shooting pain
  • Pain when chewing
  • Sensitivity to hot or cold
  • Bitter taste in the mouth
  • Bad breath or mouth odor
  • Fever
  • Swollen glands in the neck
  • General discomfort or feeling unwell
  • Swelling in the upper or lower jaw

Swelling in the jaw is a serious symptom and should be evaluated by a pediatric dentist in New Hampshire as soon as possible.

Understanding Child Dental Infections

When bacteria enter the inner portion of the tooth, the body naturally attempts to fight the infection. In many cases, this response leads to the formation of an abscess, which is a pocket of infection that develops beneath the surface of the gums. This can result in increased pressure, swelling, and significant pain.

An infection may also develop when dead cells and tissue become trapped within the tooth. While the body is normally able to eliminate these substances, a blockage can allow toxins to build up, leading to infection. A kids dentist can identify the cause and recommend the appropriate treatment to restore your child’s oral health.

Abscess and Its Impact on Kids

When an infection reaches the pulp of the tooth, the body responds with inflammation as it attempts to contain the bacteria. This may lead to the formation of a visible lump on the gums filled with pus and infected material. Pus is a protein rich fluid that helps trap and isolate harmful substances.

An abscess can be extremely painful and should not be ignored. Without proper treatment, the infection can spread and lead to more serious health concerns. Seeking care from a pediatric dentist in New Hampshire ensures that the infection is properly treated and managed.

Why Prompt Dental Treatment Matters

Some minor infections may appear to improve temporarily, but relying on the body alone to resolve a dental infection is not recommended. Delaying treatment can lead to worsening symptoms and potential complications affecting your child’s overall health.

As part of our commitment to children’s dental care in New Hampshire, we encourage parents to seek professional care at the first sign of infection. Early diagnosis and treatment by a kids dentist can relieve pain, stop the spread of infection, and protect your child’s developing smile.

Dr. Wilson and our team are here to provide gentle, effective care when your child needs it most. If you suspect a tooth infection, contact our office right away so we can help restore your child’s comfort and oral health.

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!
