Hello,
I can understand your concern. Was your son born with dark tongue and discolored tongue? If that is the case, then there seems to be problem in the development of the teeth and tongue and it might be difficult to cure.
However, if the black tongue and discoloration of the teeth have developed after birth, then it might be due to inadequate
oral hygiene. When oral hygiene is not maintained well,
plaque and debris accumulate on the tongue and teeth which may cause the discoloration or yellow discoloration.
I would advise you to visit a pedodontist,
dentist who specializes in the treatment of oral cavity of children or a dentist and go for ultrasonic scaling, which is the process which cleans the plaque, calculus (
tartar) and debris from the teeth. He/she might also advise to use a mouthwash and about the care of tongue.
I hope this information helps you. Thank you for choosing HealthcareMagic. Take care.
Best,
Dr. Viraj Shah
