When you have a toothache or dental infection that is causing you pain, how can you find relief? In some cases, your dentist may prescribe an antibiotic. It may seem odd to take the same medicine for a toothache that you might take for a respiratory or ear infection. However, all infections‚ even those in the mouth, have something in common: They are caused by bacteria. That said, not all toothaches require antibiotics, so your dentist will decide when they are or aren’t needed.
Bacteria and Tooth Decay
To understand why your dentist might prescribe antibiotics for a toothache, you must first understand how bacteria contribute to tooth decay and toothaches. Without regular, twice-daily brushing with proper technique, the bacteria in your mouth can grow and turn the foods you eat into plaque and tartar that then gets deposited on your teeth. This promotes cavity formation and tooth decay.
Common Toothache Causes and Treatments
When bacteria start to break down your tooth structure it can form a cavity that can either be fixed by your dentist with a simple filling or a crown. But if the cavity is not stopped early enough the decay can continue to grow and eventually reach the center of the tooth where the nerves are. Once the nerves become affected by the decay this can cause immense amounts of pain, and lead to an infection.
When a tooth infection reaches the nerve of the tooth, it may require a root canal and a protective cover to seal bacteria out of the tooth. Additionally, if a tooth is so broken down by a cavity that it can’t be repaired, the dentist may need to extract the tooth.
When Does a Toothache Require Antibiotics?
When the dental infection is severe or impacts the gum around an erupting tooth, your dentist may recommend antibiotics. For instance, pericoronitis is an infection in the gum tissue that can develop around impacted wisdom teeth. Patients with this condition may be given antibiotics as part of their treatment.
Additionally, if your dentist notices signs of a dental abscess‚ a tooth infection that can develop from an untreated cavity, they may recommend antibiotics.
Taking Antibiotics for Oral Infections
For dental infections, dentists will often prescribe penicillin or amoxicillin. Clindamycin is also a commonly prescribed alternative for those allergic to penicillin. Your dentist will be sure to identify the right dose and duration of medication for your particular situation. Because over-prescription of antibiotics can sometimes lead to more resistant strains of bacteria, your dentist will also take antibiotic resistance into consideration when they prescribe your dose.
It’s important to take the full course of pills exactly as your dentist prescribes for the best outcome. Just remember, even if the pain resolves, you’ll likely still need further treatment to fully restore your tooth.
Toothache Prevention
There are many ways to help prevent toothaches. Following these steps can help you reduce your risk of cavities or a toothache:
- Limit your frequency and intake of sugary foods and drinks.
- Brush your teeth with fluoride toothpaste twice daily to decrease the sugar and bacteria accumulation on your teeth.
- Floss between your teeth, once a day, to prevent cavities from forming where your teeth touch.
- Maintain regular checkup appointments so that your dentist can continue monitoring your risk of cavity formation.
You can take steps to help prevent cavities and tooth infections. However, if you already have one, know that your dentist has your best interests in mind if they prescribe you antibiotics for a toothache.
