Smoking can certainly leave a lot of staining. Much of it is superficial but some also gets deeply engrained into the tooth. Superficial staining can be removed during your professional
cleaning by your dental hygienist with the polishing and professional cleaning. Certain home care tools can certainly help as well such as a high quality electric toothbrush and flossing. At the very least these great home care tools can help prevent further staining or allow longer before the stain builds up. You may also be a candidate after the
professional cleaning for in office or at home whitening options. In addition to all this, your dental office will need to work with you to evaluate with an examination of the gums and the bone and dental X-rays to see the health of the bone and gums. Smoking is known to cause periodontal disease or bone loss; so in addition to the stain, it would be important to
know the overall health of the teeth and gums. Smoking cessation would ultimately be the healthiest option; if that is not possible, the above pointers will help keep your smile whiter and brighter.
Several things can cause gums to bleed, including plaque buildup along the gum line and between teeth. Plaque is a layer of sticky bacteria that constantly forms on teeth. If you don't get rid of plaque by flossing daily, it leads hardened plaque deposits (called calculus or tartar) and this leads to gum inflammation called gingivitis. Note that is hard to remove calculus without a dentist's or dental hygienists help through a professional cleaning. So, your first line of defense against bleeding gums should always be a visit with your dentist, who would be able to alert you if there's an underlying condition for your bleeding gums. A dental examination with x-rays can help to determine if there is any tartar buildup and resulting bone loss/ periodontal disease and any next steps for treatment.
Other causes of bleeding gums include vitamin deficiencies, smoking, hormonal changes, etc. so it is difficult to completely determine the exact cause without a professional examination.
In the meantime, eat a well balanced diet to develop and maintain strong, decay-resistant teeth. Brush your teeth at least twice each day and continue to floss. Salt water or antibacterial rinses may also help you in the interim and provide some relief for your painful gums. If you're not sure you're brushing or flossing correctly, you can ask your dental hygienist for some tips, and if you smoke, consider options to help you quit.
