Nowadays, life is fast-paced and work is stressful, so there are few people who smoke to reduce stress. But cigarettes are very harmful, not only cause lung disease, cardiovascular disease, etc., but also induce the appearance of cancer, which is very bad for human body. For dental implant patients, both before and after the implant, the doctor will clearly tell you to abstain from smoking. This is because the harmful substances in cigarettes, such as nicotine and tar, will invade the periodontal tissues, accelerate the loss of calcium from the alveolar bone, and hinder the healing of the wound. Therefore, smoking can greatly reduce the success rate of dental implants. Although the effect of dental implants is good, post-operative dental maintenance is also important. For real teeth, frequent smoking will make the teeth yellow and black and induce oral diseases such as periodontitis and gingivitis, and for dental implants, smoking is even more harmful and will directly affect the life of dental implants. Although dental implants are a perfect substitute for real teeth and are known as the “third tooth of mankind”, they are different from real teeth and require extra care to prolong their life. In fact, before getting dental implants, the doctor must ask the patient to quit smoking. Smoking affects oral hygiene, and tobacco stains are a very common phenomenon. Cigarettes can hinder the growth of epithelial tissue or wound healing, and dental implants are a special process where the gaps opened during implant placement need to heal. The ability to heal wounds in normal people decreases with age. Data show that the wound healing ability of a 50 year old smoker is only equivalent to that of a 68 year old non-smoker, which means that the wound healing ability of a smoker is less than 30% of that of a non-smoker. Smoking can cause inflammation around the implant, which can affect the resorption of the alveolar bone and lead to dental implant failure. It has been proven that the success rate of implant surgery decreases by about 40% in smokers who smoke more than 5 times a day. If a smoker smokes more than 10 cigarettes a day, the implant failure rate will be twice as high as that of non-smokers. Even if the initial implant is lucky to survive, smoking after the implant is done may cause the root of the implant to loosen, making the implant poorly anchored and prone to fall out. In particular, you should not smoke or drink for two weeks after the implant surgery to prevent tobacco and alcohol from irritating the wound and causing infection. In addition to quitting smoking, you should also pay attention after dental implant surgery: 1. 2~3 days after surgery, please use mouthwash and do not brush your teeth in the surgical area; 2. 2 weeks after surgery, no smoking and no alcohol, and after two weeks, quit smoking by the way; 3. If you have done maxillary sinus implant surgery, do not blow your nose or spit hard; 4. If the bleeding is heavy, bite the gauze block with cool water, if you still cannot stop the bleeding, you should go to the hospital immediately; 5. 2-3 days after surgery, the surgical 5. 2-3 days after surgery, there may be some swelling in the area, cold compresses for two days after surgery, after that hot compresses can be applied to help reduce the swelling.
