When a tooth has to come out
Extraction is the last option, not the first. It is considered when:
- a tooth is too decayed or fractured to restore
- severe gum disease has destroyed the bone supporting it
- a wisdom tooth is impacted and causing pain, infection or damage to the tooth in front
- an infection cannot be resolved by root canal treatment
- occasionally, to make room before orthodontic treatment
Where a tooth can be saved with a filling, a crown or a root canal, that is almost always the better outcome. A natural tooth keeps the bone and gum around it healthy in a way no replacement fully matches, so an examination and X-rays come first, to be sure the tooth really cannot be kept.
A simple extraction removes a tooth that is visible and accessible, under local anesthetic. The tooth is loosened in its socket and lifted out. You feel pressure but should not feel pain.
A surgical extraction is needed when a tooth is broken at the gum line or impacted, and may involve a small incision in the gum and sometimes sectioning the tooth to remove it in pieces. Stitches are sometimes placed afterward. Impacted wisdom teeth are usually planned from X-rays or a 3D cone beam scan that shows how close the roots sit to the nerve.
Tell the dentist about every medication you take before an extraction — particularly blood thinners and bone medications — and about any heart condition or joint replacement. They change how an extraction is planned.
Aftercare — the part that matters
A blood clot forms in the socket and protects the bone underneath while it heals. Dislodging it causes dry socket, which is painful and delays healing.
For the first 24 hours: no smoking, no drinking through a straw, no vigorous rinsing or spitting. Bite gently on gauze until bleeding stops, use a cold compress on the outside of the cheek, keep your head elevated, and eat soft food. From the next day, gentle rinses with warm salt water help keep the area clean. Brush the other teeth as normal, taking care around the socket.
Increasing pain two to four days later, rather than improving pain, is the classic sign of dry socket — call the office. So is bleeding that does not slow with firm pressure, a fever, or swelling that is getting worse after the third day. Swelling that spreads toward the eye or under the jaw, or any difficulty breathing or swallowing, is a medical emergency.
Replacing the tooth
Unless it is a wisdom tooth, plan for what fills the space. Teeth drift into gaps and bone resorbs where a root used to be, so the options are generally easier the sooner they are considered — ideally before the extraction.
The usual choices are a dental implant, a bridge or a partial or full denture. Where an implant is likely later, a bone graft placed in the socket at the time of the extraction can preserve the bone it will need. The restorative dentistry page compares them side by side.
Frequently Asked Questions
Does an extraction hurt?
The area is fully numbed, so the sensation during the extraction is pressure rather than pain. Soreness afterward is normal and is usually manageable with over-the-counter pain relief, taken as directed.
How long is recovery?
The gum is typically comfortable within a few days to a week after a simple extraction, and longer after a surgical one. The bone underneath takes considerably longer — several weeks to months — to fill in.
What is dry socket?
Dry socket happens when the blood clot in the socket is dislodged or dissolves early, leaving bone exposed. The classic sign is pain that increases two to four days after the extraction instead of easing. It is treatable, so call rather than wait it out.
What can I eat afterward?
Soft, cool or lukewarm food for the first day or two — yogurt, eggs, soup that is not hot, mashed vegetables — chewing on the other side. Avoid drinking through a straw, and avoid alcohol while the socket is healing.
When can I smoke after an extraction?
Ideally not at all while the socket heals, and at the very least not for the first 24 to 48 hours. Smoking is one of the main causes of dry socket and slows healing.
Do I need to replace the tooth?
Usually, unless it is a wisdom tooth. Neighboring teeth drift into the space and the bone where the root was gradually shrinks, so an implant, bridge or partial denture is easier to plan if it is considered before or soon after the extraction.
