A toothache (pulpitis) is when the pulp inside a tooth becomes inflamed and infected. The pulp is the soft part inside the tooth that has blood vessels and nerves.
A toothache often happens after an injury to the tooth. The most common form of injury to a tooth is from a cavity. This is a hole in a tooth.
A cavity is often the result of poor dental hygiene. Sugar and starch in foods allow bacteria in the mouth to damage the teeth. The bacteria in the mouth feed on sugar and starch and make an acid that can eat through the teeth. This leads to tooth decay.
Each child may feel symptoms a bit differently. But below are the most common symptoms of a toothache:
Constant, throbbing pain in a tooth
Pain in the tooth that gets worse when the tooth is touched
Pain in the tooth that gets worse with hot or cold foods or liquids
A sore, tender jaw around the tooth
Generally tired and feeling badly (malaise)
Your child’s healthcare provider can often diagnose a toothache with a complete health history and exam of your child. He or she will likely refer your child to a dentist for evaluation and care.
At the dentist, your child may have X-rays done. An X-ray makes images of internal tissues, bones, and teeth. The dentist may also check for cavities using a device called a transilluminator. It uses no radiation.
The symptoms of a toothache may seem like other health or dental problems. Make sure your child sees his or her healthcare provider or dentist for a diagnosis.
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
Treatment may include:
Warm saltwater rinses for the mouth
Draining a pus-filled infection (abscess), if needed
A simple filling, if needed
Surgery to remove the inflamed pulp from the middle of the tooth (root canal)
If the infection is severe, your child may be treated in a hospital. He or she may need antibiotics through an IV (intravenous) tube.
Good oral habits can prevent cavities, the leading reason for a toothache. Make sure your child:
Brushes his or her teeth twice a day
Sees the dentist regularly. The dentist can find and treat cavities early before they cause damage to the pulp. He or she can also give treatments to stop cavities from happening.
Eats healthy foods, limiting those high in sugar and starch
A toothache is when the pulp inside a tooth becomes inflamed and infected.
Most toothaches are caused by cavities.
Besides pain, a toothache may cause fever and a general feeling of tiredness (malaise).
X-rays can diagnose problems within the tooth.
Treatment may include antibiotics, pain medicine, a filling, or removal of the tooth.
Toothaches can be prevented with good oral care.
Tips to help you get the most from a visit to your child’s healthcare provider:
Know the reason for the visit and what you want to happen.
Before your visit, write down questions you want answered.
At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
Ask if your child’s condition can be treated in other ways.
Know why a test or procedure is recommended and what the results could mean.
Know what to expect if your child does not take the medicine or have the test or procedure.
If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
Know how you can contact your child’s provider after office hours. This is important if your child becomes ill and you have questions or need advice.
