Evident Signs of Infection After Oral Biopsy

Infections after oral biopsies are very rare, but if they do happen. They usually target people with weaker immune systems. Therefore, it’s crucial to watch out for some apparent signs of infection after the oral biopsy to seek timely treatment.

Care Instructions After an Oral Biopsy

The majority of people go through an oral biopsy with minimal side effects. However, some short-term symptoms include:


  • It’s normal to have some bleeding or oozing overnight after surgery.
  • To control bleeding, put fresh gauze moistened with tap water on the area and gently press down.

Persistent Bleeding

  • Bleeding shouldn’t be heavy. If it continues, apply steady pressure with moistened gauze for 30 minutes.
  • If bleeding still doesn’t stop, try using a moistened tea bag wrapped in gauze for 20-30 minutes.
  • If bleeding keeps going, call our office for help.

Reducing Swelling

  • Swelling is common after oral surgery.
  • To reduce swelling, use a cold pack, ice bag, or frozen peas wrapped in a towel.
  • Apply it gently to the surgical area for twenty minutes at a time, with twenty-minute breaks, during the first day after surgery.

Signs of Infection Post Oral Biopsy

If you notice any of the following symptoms 3-4 days after the mouth biopsy, it is likely infected. Seek immediate help from an emergency room.

  • A swollen area near the surgery site that’s bright red and getting bigger instead of smaller.
  • A high temperature of 101 degrees Fahrenheit or higher.
  • Intense pain that’s not getting better with medication.
  • Pus or fluid coming from the surgery site, which might have a bad taste or smell.

How Long Does It Take for a Mouth Biopsy to Heal?

Healing time after an oral biopsy can vary from 2-3 days to 2 weeks, depending on where and how the biopsy was done. If the biopsy was done with just local anesthesia and no stitches, you can feel pain and discomfort for the first 2-3 days. After that, you should start feeling better bit by bit.

What to Eat After Oral Biopsy?

After an oral biopsy, it’s important to eat soft foods that are easy to chew. These foods should be rich in vitamins, minerals, energy, and protein to help your wound heal. For the first 2 days after surgery, stick to liquids and soft foods. On day 3, you can start eating soft foods that don’t need much chewing. Following are some soft-diet suggestions:

  • Anything that’s been blended in a food blender
  • Cream of Wheat, oatmeal, mashed avocado, applesauce
  • Mashed or baked potatoes with butter or sour cream
  • Mashed banana or other mashed/blended fruits
  • Broth or creamy soup
  • Mashed steamed vegetables like yams, sweet potatoes, or butternut squash
  • Cottage cheese, cream cheese, or soft cheese
  • Creamy peanut butter without solid pieces
  • Eggs can be cooked anyway, with or without melted cheese; omelets can have cheese and avocado.
  • Jell-O, pudding, ice cream, yogurt
  • Milkshakes or smoothies (avoid blending with berries that have seeds)
