Key Takeaway

You can develop bad breath after wisdom teeth removal due to bacteria feeding on trapped food, decaying tissue, or byproducts of the healing process. To fix this, maintain proper oral hygiene, rinse with salt water, stay hydrated, and avoid disturbing the surgical site.

Why Do I Have Bad Breath After Wisdom Teeth Removal?

Bad breath after wisdom teeth removal is common and typically results from temporary changes in your mouth during healing.

  • Blood clot formation: The body forms a protective blood clot at the extraction site to promote healing. As this clot breaks down, it releases proteins and byproducts that attract bacteria. The bacteria feed on these substances, producing foul-smelling gases that cause bad breath.
  • Bacterial growth in the tooth socket: When food particles get trapped in the extraction site, they become a food source for bacteria. These bacteria multiply quickly and release sulphur compounds, which are responsible for the unpleasant smell associated with bad breath.
  • Dry socket (a painful condition): If the blood clot protecting the extraction site dislodges or dissolves too soon, it exposes the underlying bone and nerves. This condition, known as a dry socket, allows anaerobic bacteria to thrive and release gases with a foul odor, while also causing severe pain.
  • Food particles and debris: Leftover food particles can become lodged in the tooth socket, creating a breeding ground for bacterial growth. As bacteria break down these particles, they produce odorous byproducts that lead to bad breath and a bad taste.
  • Dry mouth due to decreased saliva production: Saliva is essential for washing away bacteria and food debris. After surgery, pain medications and reduced fluid intake can cause dry mouth, allowing bacteria to multiply and contribute to bad breath.
  • Post-surgery healing process: During the natural healing process, tissues release byproducts like dead cells and proteins that bacteria can feed on. As bacteria break down these substances, they release foul-smelling gases, contributing to bad breath.

How to Get Rid of Bad Breath After Wisdom Teeth Removal

Good oral hygiene and proper aftercare can keep bad breath at bay and support a smooth recovery.

  1. Rinse gently with warm salt water: Salt water rinses help clean the area, reduce bacterial infections, and promote proper healing. Use lukewarm water and rinse 2-3 times a day (especially after meals), but avoid vigorous rinsing.
  2. Maintain good oral hygiene: Use a soft-bristled toothbrush to gently clean your teeth while avoiding the extraction site. Proper brushing and antibacterial mouthwash (if prescribed) help control bacterial plaque.
  3. Stay hydrated by drinking plenty of water: Hydration boosts saliva production and keeps your mouth moist, helping prevent dry mouth and foul breath.
  4. Eat soft foods: Stick to soft foods like yogurt, mashed potatoes, and soups. Check out this blog for a list of 50 soft foods to eat after wisdom tooth extraction. Avoid crunchy foods and acidic foods that may irritate the extraction site.
  5. Avoid mouthwash with alcohol: Alcohol-based mouthwashes can dry out your mouth and delay healing. Only use the mouthwash your oral surgeon prescribes. 

While bad breath is normal after wisdom tooth removal, there are a few things you should watch for that may indicate that something is wrong. 

  • Persistent foul odor or unpleasant taste: This could be a sign of infection after tooth extraction.
  • Intense pain or severe pain: May indicate a dry socket or another post-extraction complication.
  • Foul-smelling discharge or unusual discharge: This can be a sign of bacterial infections.
  • Persistent swelling: If swelling does not reduce, contact your oral surgeon.
