Smoking, vaping and oral health

Smoking is linked with oral health problems including gum disease and delayed healing. Vaping should not be presented as harmless.

Smoking is associated with gum disease, oral health problems and poorer healing after dental treatment. Stopping smoking can support general and oral health.

Vaping is often discussed in relation to stopping smoking, but it should not be described as harmless. Ask a healthcare professional for stop-smoking support rather than relying on dental advice alone.
