How Long Do Canker Sores Last? – Different Healing Stages and Home Remedies

Different Stages of Healing

As we said earlier, canker sores usually heal without any treatment in a couple of weeks. There are three stages of healing:

1. Prodromal or Beginning Stage – It is the pre-ulcer stage, i.e. period before the formation of ulcers. It usually lasts for one to three days. You may feel a prickling or burning sensation during this initial period, which leaves a raised, reddened, painful area on the mucus membrane of the cheek or lips.

• Ulcer Stage – It is usually three to six days (may remain longer in some people). The formation of ulcers is completed, characterized by redness and excessive pain.

• Healing Stage – The healing stage usually begins nine to ten days after the initial stage. During this stage, the healthy tissue starts working on sore, and pain starts fading away. Ulcer also starts getting smaller.

Symptoms and complications of the healing stage depend on the type of ulcer

• Mild canker sores heal within a couple of weeks.
• Major canker sores may remain for a few weeks and can be painful for a long time. They often create a scar on the affected area.
• Herpetiform canker sores are rare types of sores and fade away after ten to four days without causing any scar.

• What is the white stuff in a canker sore?

There is no white “stuff” in or around the canker sores. The middle part of the sore becomes white, yellow, or sometimes grey due to the injury to surrounding tissues. Tissues are injured, and hence the blood supply to the injured area is deprived, and the area starts looking white, yellow, or grey.

• Can canker sores last for months?

No, canker sores don’t last for more than two or a maximum of three weeks. If they don’t heal even after three weeks, there is probably an underlying condition like prolonged constipation, excessive bowel gas, inflammatory bowel syndrome, habitual smoking, emotional stress, etc. If you are unable to overcome canker sores for so long, you must get proper medical attention to find out the exact cause and get treatment accordingly.
