Tooth extraction sites sometimes have a whitish appearance while they are healing and you could still have some swelling where the tooth was removed.
The white tissue (granulation tissue) is part of a normal healing process.
It should look less and less white every day. But, it will take longer than two days to heal. The area should be feeling better each day. How your mouth feels is more important than how it looks. Even when healthy, extraction sites may look worrisome to the untrained eye. It is important to leave the area undisturbed for at least 24 hours after the extraction. After the first 24 hours gentle rinsing is recommended.
Depending on how difficult the extraction was, it could take weeks for the area to heal completely and look 100% normal but it takes a lot less time for it to feel good. Removing a tooth traumatizes the bone and gum tissue near the tooth extraction site. Some swelling and soreness is normal but should gradually improve.
If the swelling doesn't improve or if you have any concerns about how it is healing, you should call your dentist...having it checked is the only way to know for sure that you are healing properly. These are general guidelines and should't be used in place of your dentist's advice.
Most dentists and oral surgeons advise clients to avoid chewing on the side where the tooth was removed.
A soft diet is a good idea.
Try to leave the area undisturbed as much as possible for the first 24 hours.
An antibiotic or pain medicine may be prescribed.
Gently rinsing the area after 24 hours is usually recommended.
Post extraction care instructions vary depending on the dentist and the type of extraction (an erupted tooth vs an impacted one and presence or absence of infection). If you have questions regarding tooth extraction aftercare, ask your dentist.
When a tooth is removed, a blood clot forms in the socket...the hole that is left after the tooth is gone. The clot is needed to help the tooth extraction site heal properly.
A dry socket occurs a few days after a tooth extraction if the blood clot comes out. A dry socket is very painful. More about dry socket here.
Taking good care of your extraction site will make getting a dry socket less likely.
Here is some additional info on after care. This article is about wisdom teeth, but some of the information applies to any tooth extraction.
