His Canine tooth ( upper jaw) is totally not there .... But his right side one is .... Is this normal or perhaps he needs to grow it ? He is 6 yrs this yr ... Also I noticed one of his incisors is chipped where the tooth meets the gum... Could this be causing him any pain ? His gums look pretty healthy in general but I am yet to get a dentist out to him. When I put the bit ( 5.5 inch standard snaffle) in he is fine , he chomps a little but after about five mins he settles. He isn't head shy just doesn't like the fuss of fitting a new head piece. Any suggestions or thoughts ? Is there a supplement designed to help with teeth ?
