Should you use an antibiotic to get rid of bad taste in your mouth due failed root canal?

It is recommended that you consult a dentist or medical professional for accurate advice regarding medical conditions. Treating a bad taste in your mouth due to a failed root canal may not be appropriate for antibiotics. Here's what you should do:

1. Seek Dental Evaluation:

- Visit a dentist to address the failed root canal. They will assess the root canal's condition, determine the cause of the bad taste, and recommend the best course of treatment.

2. Avoid Self-Treatment:

- Antibiotics are not always the solution for a bad taste in your mouth. Misusing antibiotics can lead to antibiotic resistance, making future infections harder to treat.

3. Dentist-Recommended Care:

- Your dentist may recommend treatments like root canal retreatment, extraction of the affected tooth, or other procedures based on the root canal's failure.

4. Address Underlying Causes:

- The bad taste could have various causes beyond the failed root canal, such as sinus issues, gastrointestinal problems, or poor oral hygiene. Your dentist will rule out these possibilities.

Remember, a dentist's professional advice and treatment are crucial in managing dental issues like failed root canals. Antibiotics may be necessary in certain cases, but using them without proper evaluation can have harmful consequences.
