You have undergone soft tissue surgery to an area in the mouth. The wound has been closed with stitches and will require a period of healing over the coming days and weeks.
What to Expect After the Procedure
Pain and Discomfort
Once the local anaesthetic wears off, it is normal to experience mild to moderate discomfort at the surgical site. This is usually most noticeable during the first 2-3 days and can generally be managed with paracetamol and ibuprofen taken as directed.
Swelling
Minor swelling is common and may increase during the first 48-72 hours before gradually improving.
Bleeding
A small amount of blood staining or oozing is common during the first 24 hours. If bleeding occurs, apply firm pressure with a clean gauze swab or handkerchief for 20 minutes without repeatedly checking the area.
Stitches
Most stitches used inside the mouth are dissolvable and will usually soften and fall out within 2-3 weeks. Occasionally they may come away earlier as the wound heals.
Appearance of the Wound
The surgical site may initially appear white, yellow, or grey. This is a normal part of healing and does not necessarily indicate infection.
What To Do After the Procedure
Pain Relief
Take painkillers (usually both paracetamol and ibuprofen) as soon as possible after the procedure, so that they are working when the local anaesthetic wears off. Continue to take painkillers regularly for the first few days, whether or not you are in pain.
Sleeping
Sleep on several extra pillows for the first two nights, so that your head is more elevated than usual. This helps the swelling go down more quickly. It may be beneficial to place a towel over the pillow if there is blood in your saliva.
Oral Hygiene
Good oral hygiene is important for healing.
- Continue brushing your teeth normally
- Avoid direct trauma from the toothbrush to the surgical site during the first few days
- From 24 hours after surgery, rinse gently with warm water after meals and before bed
Diet
For the first few days:
- Eat soft foods
- Chew on the opposite side if possible
- Avoid hard, sharp, crunchy, spicy, or very hot foods that may irritate the wound
Examples of suitable foods include pasta, yoghurt, soup, eggs, fish, and mashed potato.
Smoking and Vaping
If you usually smoke or vape, avoid this for as long as possible after surgery. Smoking delays wound healing, increases the risk of infection, and can worsen discomfort.
Activity
Avoid strenuous exercise and heavy physical activity for the first 24-48 hours, as this may increase bleeding and swelling.
Histology Results
If tissue has been removed for microscopic examination, it will be sent to the laboratory for analysis.
Results are usually available within 2-3 weeks and will be discussed at your follow-up appointment or communicated separately.

Frequently Asked Questions
How Long Does a Mouth Biopsy Take to Heal?
Most soft tissue biopsies heal significantly within 2 weeks, although complete maturation of the tissues may take several weeks longer.
Is White Tissue Normal After a Mouth Biopsy?
Yes. The wound often develops a white, yellow, or grey covering during healing. This is a normal part of the healing process and is not necessarily a sign of infection.
When Will My Mouth Stitches Dissolve?
Most dissolvable stitches used inside the mouth begin to soften after 2 weeks and usually disappear within 2-4 weeks.
What Can I Eat After a Mouth Biopsy?
Soft foods are generally best for the first few days. Avoid hard, crunchy, spicy, or very hot foods while the site is healing.
Is Swelling Normal After an Oral Biopsy?
Yes. Swelling usually worsenswithin the first 2-3 days before gradually improving.
How Long Will the Biopsy Results Take?
In most cases, pathology results become available within 1-3 weeks, depending on the type of specimen and laboratory processing times.
Clinic Review
A review appointment will typically be made 2 weeks after your surgery, in order to check healing and discuss histology results.
