The eruption and shedding schedule of the deciduous teeth is subjective and varies from patient to patient. Discrepancy of plus minus 3 months is considered acceptable. You can wait for sometime because even if you visit a dentist, the position of the teeth in the bone cannot be evaluated without an x-ray which should not be the first plan of action. If the delay is too long then an x-ray will be recommended and will be done. Regards.

Dear mom, Teething is a natural process which may begin as early as 4 months and sometimes as late as 2 years. It is advisable to take your child for heir first dental visit by the time it's their first birthday. Please visit a Pediatric dentist who will be able to examine your son personally and give you the best advise possible. - Dr. Rachayta Parikh Gala Pediatric and Preventive Dentist Milky Whites Dental Home for Kids
