You can use desensitising paste. If it persist visit your dentist for complete oral prophylaxis. Regards Dental Galaxy, Pune

Hi! If your teeth are yellow and you also experience sensitivity to hot and cold, it may be due to enamel thinning or surface staining. To manage sensitivity, you should start using a desensitizing toothpaste like Sensodyne or Colgate Sensitive twice daily and avoid very hot or cold foods and drinks. Brush gently with a soft-bristle toothbrush to avoid further damage to the enamel. For yellow teeth, there are several options available, such as scaling and polishing to remove surface stains, teeth whitening (bleaching) once the sensitivity is under control, and veneers for a long-term and more aesthetic solution, especially if the discoloration is severe. It’s highly recommended to visit a dental clinic for a proper clinical checkup so the dentist can assess your condition and suggest the most suitable treatment for your teeth.

Hi, Visit a dentist and get a clinical examination.

Hello Please visit the dentist for the scaling and that will give you relief from yellow teeth and bad gums
