hello and welcome to hcm,
your teeth is effected by periodontitis
which is localised in nature.
the tingling pain
is due to sensitivity as a result of gingival recession
and pocket formation.
white around the tooth is due to deposition of food debris over there which caused the formation of heavy band of plaque called calculus.
visit your dentist
and get the cleaning and root planning treatments. use desensitising pastes like sensodent to brush your teeth.use soft-bristled toothbrush to clean your teeth.
