Smoking and vaping harm oral health in multiple ways. Quitting is the best choice for your teeth and overall health.
How smoking damages teeth
- Staining — yellows and darkens teeth
- Gum disease — increases risk dramatically
- Healing problems — after dental work or injury, smoking slows recovery
- Bone loss — smoking accelerates bone loss in the jaw
- Oral cancer risk — significant increase
- Bad breath — persistent and hard to mask
How vaping damages teeth
- Dry mouth — increases cavity risk
- Gum inflammation — nicotine damages gum tissues
- Infection risk — impaired healing and immune response
- Enamel erosion — some vaping liquids are acidic
- Oral cancer risk — still being studied, but concern exists
Health consequences
- Tooth loss — smoking is a major cause in adults
- Oral cancer — lips, tongue, throat
- Gum recession — can’t be reversed
- Delayed healing — after extractions or surgery
Quitting helps
- Gum disease stops progressing — if caught early
- Risk of oral cancer decreases — significantly within 5 years
- Healing improves — after dental work
- Teeth can be whitened — removing stains
