Please try and see a peadiatrician for proper evaluation. My cut his first tooth 11 months and two weeks,I was so worried before then.

Teething usually begins around 6 months of age. The lower front teeth usually come in first. Upper front teeth usually come in 1 to 2 months after the lower front teeth. However, it is normal for teething to start at any time between 3 months and 12 months of age. By the time your child is about 3 years old, he or she will have all 20 primary teeth.
