... a routine dental exam where her CPITN readings were 121 in the upper and 111 in the lower arch. She had given birth to her first baby two months prior. She then presented 15 months later with CPITN readings of 443 (U) and 343 (L). Is there any evidence linking breast feeding to this degree of change? Or are there any other factors in an otherwise healthy individual with fair oral hygiene. Nb. she had fixed orthodontics when she was around 16yo
