Metronidazole 400mg Tablets for Dental Infections Summary
Metronidazole 400mg Tablets (Dental Infections) Information
What Are Metronidazole Tablets?
Metronidazole 400mg tablets are a type of antibiotic that can treat tooth infections as well as other dental infections. You may be given this treatment for tooth abscesses, gum infections or deeper dental infections.
How Does Metronidazole Treat Dental Infections?
Metronidazole treats dental infections by killing anaerobic bacteria. These are the bacteria that grow without oxygen and can cause infections and abscesses in your mouth. By disrupting the bacteria’s DNA, metronidazole stops them from growing and multiplying. This helps to reduce swelling, pain and pressure around your tooth or gums, and stops the infection from spreading throughout your mouth.
Alternatives to Metronidazole Tablets
Depending on the type of bacteria causing your oral infection, you may need a different antibiotic to treat it. In some cases, your prescriber may suggest treatments such as amoxicillin, clarithromycin or co-amoxiclav. This will also depend on your medical history and can be discussed during your consultation.
How to Use Metronidazole 400mg Tablets for Dental Infections
Swallow the tablets whole with a drink of water, either with food or just after eating. Never chew or crush the medicine. The initial dose for most bacterial infections is 800mg (two tablets), followed by 400mg every eight hours. Always take metronidazole exactly as directed. If you’re unsure how much to take and how often, speak to your prescriber.
Even if your symptoms improve, it’s still important to finish the full course of metronidazole to make sure that your tooth infection doesn’t come back.

Warnings
Don’t drink any alcohol while you’re taking metronidazole for your dental infection, or for 48 hours after you’ve finished your course. Drinking alcohol while using this treatment can cause unpleasant side effects, such as feeling or being sick, stomach pain, hot flushes, a very fast or irregular heartbeat, or headaches.
If you have liver problems, nervous system conditions or allergies to antibiotics, you should mention these during your consultation so your prescriber can ensure metronidazole is safe for you to use.
If you’re pregnant or trying to become pregnant, you shouldn’t use metronidazole unless absolutely necessary. If breastfeeding, it’s best to avoid it, as small amounts of metronidazole may pass to your infant.
For all warnings and side effects, please see the Patient Information Leaflet.
Metronidazole for Dental Infections FAQs
How does Metronidazole for tooth and other dental infections work?
Anaerobic bacteria are the main cause of tooth infections, abscesses and gum swelling. Metronidazole kills these bacteria by disrupting their DNA, which stops them from growing. This helps reduce pain, pressure and swelling, and also stops the infection from spreading into the surrounding tissues in your mouth.
How long does Metronidazole for dental infections take to work?
Many tooth infections start to improve within two to three days, but you should always finish the full course of tablets to make sure the infection doesn’t come back. Your symptoms may ease before your course is completed. It’s still important to take all the treatment as directed.
Do I still need to see a dentist when using Metronidazole for a tooth infection?
Metronidazole can help clear the tooth infection, but it can’t treat the underlying cause. Dental infections are usually caused by issues such as a damaged tooth or an abscess. These can only be treated by a dentist, so you should arrange to see yours as soon as possible.
Can I drink alcohol while taking Metronidazole for dental infections?
No, you should avoid drinking alcohol while taking metronidazole and for 48 hours after finishing your course. Mixing alcohol and metronidazole can cause side effects like headaches, feeling or being sick, hot flushes, stomach pain or heart palpitations.
What should I do if Metronidazole does not improve my dental infection symptoms?
If metronidazole doesn’t seem to be helping your dental infection symptoms, speak to your prescriber or dentist. You may need a different antibiotic or dental treatment to fully clear the infection. A licensed medical professional can advise you on the next steps.
Metronidazole is available following a short online consultation with one of our UK-registered prescribers.
