Smoking is usually not recommended during root canal treatment.
Root canal treatment is a relatively common minor surgery in dentistry, mainly used to treat diseases such as pulpitis and apical periodontitis, in which a hole is drilled in the tooth to open the pulp chamber, remove the necrotic pulp, and then sterilize the root canal before filling the treatment.
During the treatment, you need to ensure oral hygiene, and cigarettes contain nicotine, which tends to stimulate the oral tissues, leading to the contraction of capillaries inside the mouth, thus triggering inflammation of the gums. Nicotine also affects the repair of the soft tissues of the mouth and the absorption of the medication placed in the root canal.
Smoking also tends to reduce the body’s immune system, which may lead to inflammation, which is detrimental to oral health.
In addition to not smoking during root canal treatment, you need to avoid alcohol, avoid eating too hard food, and do a good job of oral hygiene to prevent infection.
