What to Do When Your Child Has a Tooth Infection in Somersworth, NH
If your child woke up with a swollen cheek or has been crying about tooth pain since last night, do not wait to see if it gets better on its own. Tooth infections in children do not resolve without treatment — and because baby teeth have thinner enamel and larger nerve chambers than adult teeth, infection reaches the nerve faster and can spread to surrounding tissue quickly. Here is a clear guide to help you decide what to do right now.
How Do You Know If Your Child Has a Tooth Abscess?
A tooth abscess is a pocket of infection that forms at the root of a tooth or in the surrounding gum. Recognizing it early makes treatment simpler and safer.
Look for these signs: visible swelling on the gum, cheek, or jaw; a toothache that does not stop or gets worse with pressure or hot and cold; a bad taste in the mouth or visible pus draining from the gum; fever alongside dental pain; or your child refusing to chew, eat, or open their mouth fully. Younger children who cannot describe pain may just seem unusually irritable or tired.
Swollen lymph nodes in the neck combined with any of the above symptoms mean the infection may already be spreading — that is a signal to act immediately.
Should You Call the Dentist or Go to the ER?
Facial swelling from a dental source is a medical situation, and where you go depends on how far the swelling has spread and how your child looks overall.
Call your pediatric dentist right away if:
- The gum is swollen, with or without fever
- Your child is in moderate or severe pain
- There is visible pus or a bad taste in their mouth
- Swelling appeared or got worse overnight
Go to the ER or call 911 if:
- Swelling has moved to the cheek, under the jaw, or into the neck
- Your child is having trouble swallowing or breathing
- Fever is 103°F or higher with facial swelling
- Your child looks very ill, lethargic, or confused
One important note: the ER can treat a spreading infection with IV antibiotics and keep your child safe, but they cannot perform the dental procedure that removes the source. After any ER visit for a dental infection, your child still needs an urgent dental appointment to treat the tooth itself.
Why Children's Tooth Infections Escalate Faster Than Adults'
Baby teeth are not just smaller versions of adult teeth — their structure makes them more vulnerable. The pulp chamber (the space containing the nerve and blood supply) takes up a larger proportion of a baby tooth, so bacteria do not have far to travel before the nerve is involved.
Children's immune systems are also still developing, which means their bodies are less equipped to contain an infection in one place. An abscess that stays localized in an adult can spread to the jaw, neck, or airway much faster in a child. On top of that, kids often underreport or misdescribe pain, so by the time a parent notices something is wrong, the infection may already be advanced.
There is also a long-term risk that many parents do not know about: baby tooth roots sit directly above developing permanent tooth buds. An untreated infection can damage the adult tooth underneath before it ever comes in, affecting its enamel or eruption path permanently.

What NOT to Do While You Wait for an Appointment
Do not adopt a 'wait and see' approach. Dental infections do not clear up on their own — the bacteria causing the abscess live inside the tooth structure, and no amount of rest or over-the-counter pain relief removes them.
Antibiotics prescribed at an urgent care or ER visit can reduce the spread temporarily, but they are not a cure. The infected pulp tissue inside the tooth must be physically treated or removed. Delaying that step often turns a straightforward procedure into a more complex one — or makes extraction the only option, which then requires a space maintainer to protect your child's permanent teeth.
Baby teeth hold space in the jaw and guide the eruption of adult teeth. Losing one early because of an untreated infection can shift surrounding teeth, crowd the incoming permanent tooth, and affect how your child speaks and chews for years.
What Happens at the Pediatric Dental Appointment
When you bring your child in for a tooth infection, the appointment typically starts with an exam and X-ray to confirm where the abscess is, how deep the infection goes, and whether the permanent tooth bud nearby is affected.
Treatment depends on what the X-ray shows. If the infection is limited to the upper portion of the nerve, a pulpotomy removes the infected nerve tissue while preserving the tooth — think of it as a targeted procedure rather than a full removal. If the infection is deeper, a pulpectomy removes the entire pulp. If the tooth cannot be saved, extraction is performed, often paired with a space maintainer.
After pulp treatment, a crown is usually placed over the tooth to protect it and restore its shape. Stainless steel crowns are the most common option for back teeth because they are durable and go on in a single visit. Antibiotics may be prescribed alongside treatment if the infection was spreading, but they work as a support — not a replacement for treating the tooth itself.
Will My Child Need Sedation for a Tooth Infection Visit?
Possibly, and that is not a reason to delay the appointment. Young children and kids who are already in pain are often not able to cooperate fully with an exam or procedure. Sedation allows treatment to be completed safely and comfortably, usually in fewer appointments than it would take otherwise.
Whether sedation is recommended depends on your child's age, anxiety level, and the complexity of the procedure needed. This is discussed at the appointment — you will not be asked to decide in advance without information. Treating a dental emergency under sedation also reduces the chance that the experience creates lasting fear of dental visits, which matters for your child's long-term health.

Getting Urgent Dental Care in Somersworth, NH
Somersworth sits close to Dover, Rochester, and Portsmouth — so in a true emergency, you have ER options nearby. But for the dental treatment itself, having a local pediatric practice you already have a relationship with means shorter wait times and a provider who already knows your child's history.
NH Medicaid and CHIP programs — including NH Healthy Families and WellSense — generally cover emergency dental treatment for children, so cost should not be a reason to delay calling. If you are not sure about coverage, a quick call to the office can help you figure that out before the appointment.
Acting quickly on a tooth infection protects your child from pain, prevents spread to nearby structures, and preserves the permanent teeth still developing underneath.
