I talked about my friend with a wiggly tooth earlier, from chew. he started smoking because he thinks it'll be easier on his tooth. will it?

Both dangerous!: I did not see your original post. If your friend has a wiggly tooth and "chew" refers to chewing tobacco, I have two comments. First, both chewing tobacco and smoking tobacco can cause cancer! and secondly, your friend should see a dentist to find out why his tooth is "wiggly". Avoiding that tooth does not solve the problem. Be a friend and tell him to stop smoking and see a dentist.

No: Unfortunately both chewing tobacco and smoking increase the risk of periodontal disease which causes loss of the periodontal ligament attachment, bone loss and pocket formation. Nicotine impairs the natural immune response which weakens your defense to the bacteria introduced by plaque and compromises the ability to heal. Both also increase the risk of oral cancer.

Both very bad: Chew many times leads to gingival recession and eventual bone loss....Hence the loose tooth. It also is highly implicated in various oral cancers. Everyone knows that smoking comes with it increased cancer and circulation problems. It also increases the chance and severity of periodontal disease....Leading us right back to loose teeth. Running would be a much healthier habit .....
