Keep your teeth clean. Plaque forms bacteria that irritate your gums and may make them recede.
Use desensitizing toothpaste and fluoridated dental products.
Use a soft toothbrush that won’t scratch tooth enamel or wear away gum tissue and brush gently using a circular motion.
Use warm water when brushing your teeth to soften your toothbrush’s bristles.
Avoid tobacco in any form. In addition to its cancer-causing effects, smoking cigarettes or chewing tobacco may cause gums to recede.
Reduce your intake of acidic foods and sugary snacks and drinks.
