What not to do after a tooth extraction: 9 important rules

After a tooth extraction, a blood clot forms in the tooth socket. This clot stops the bleeding, protects the bone and nerve endings, and supports the healing process. The first 24–48 hours are crucial because the blood clot is most fragile during this period.

Recommendations may vary depending on the type of extraction and your overall health, so your dentist’s instructions should always take priority.

In short, after an extraction, do not:

• Rinse your mouth vigorously;
• Touch the extraction site;
• Use a straw;
• Smoke or vape;
• Drink alcohol;
• Eat or drink anything hot;
• Eat hard, crunchy, or spicy foods;
• Engage in strenuous physical activity;
• Change your prescribed treatment without your dentist’s approval.

During this time, the blood clot forms and stabilises. If it is disturbed, the bone and nerve endings remain exposed, increasing the risk of bleeding and dry socket.

“The blood clot is the body’s natural bandage. We mustn’t interfere with it in any way; we simply need to leave it undisturbed.” – Dr Marius Goția 

Do not rinse your mouth vigorously or spit for the first 24 hours

Vigorous movements may dislodge the blood clot. Mouthwash should only be used if recommended by your dentist, and gentle rinsing is permitted after the specified period.

Do not touch the extraction site 

Avoid touching the area with your tongue, fingers, toothpicks or repeatedly ‘checking’ the wound. Every touch can reintroduce bacteria and dislodge the blood clot. If you have stitches, protect them.

Do not use a straw or create pressure in your mouth  

Suction can destabilise the blood clot. Direct evidence is limited, but this precaution is simple and free, so it is worth following.

Do not smoke or use vaping products  

Smoking delays healing and increases the risk of the clot becoming dislodged. A systematic review from 2022 analysed 11 studies; in 10 of them, dry socket was more common in smokers than in the general patient population. You should agree on the duration of abstinence with your dentist.

Do not drink alcohol after an extraction

It can increase the risk of bleeding, may interact with prescribed medication and slows down recovery. It is safest to wait until your doctor confirms that you are healing well.

Do not consume very hot food or drink  

Whilst the anaesthetic is still taking effect, the risk of burns increases, and high temperatures can cause bleeding to resume. Start with soft foods at a moderate temperature.

Do not eat hard, crunchy, spicy or sticky foods  

They can damage the wound, and fragments can easily end up in the socket. Chew on the opposite side for the time being.

Avoid strenuous physical activity  

Sport, lifting weights and repeated bending increase blood pressure and may cause the bleeding to start again. When you can resume these activities depends on the complexity of the extraction.

Do not change your medication without your doctor’s consent

Take painkillers and antibiotics as prescribed and avoid self-medication. Do not stop taking anticoagulants or antiplatelet agents on your own initiative; simple extractions can usually be carried out without stopping warfarin, provided the INR is below 4, with local haemostatic measures. The decision rests with your doctor. 

The pain and inflammation are most severe in the first few days, then gradually subside day by day. If the pain persists, you should see your dentist. 

The gum gradually closes over the site, but the healing of soft tissues differs from bone regeneration, which takes several months. 

Bone remodelling occurs most rapidly in the first 3–6 months, during which a process of bone resorption also takes place. According to studies, the alveolar ridge may recede by 29–63 per cent. Recovery may be delayed by smoking, poor oral hygiene or infections.

Dry socket occurs when the blood clot detaches or fails to form properly, leaving the bone exposed. The symptoms most commonly occur between the first and third day after extraction:  

• increasing pain;
• an unpleasant taste or smell.

The incidence varies considerably. According to some studies, dry socket can occur in between less than 1 per cent and over 25 per cent of cases involving impacted wisdom teeth. It can be prevented by avoiding:

• smoking;
• vigorous rinsing;
• trauma to the alveolus.  

“If dry alveolitis is suspected, a consultation with a dentist is required. Most complications can be avoided through a few simple measures and, above all, by communicating with your dentist.” – Dr Marius Goția 

You should make an appointment with your doctor if you experience:

• bleeding, or heavy bleeding;
• pain that gets worse after a few days;
• severe or worsening inflammation;
• fever or feeling unwell;
• discharge, an unpleasant taste or smell;
• difficulty breathing or swallowing (medical emergency);
• numbness that persists beyond the expected duration.
