Tooth Table of a Horse ( 9 - 14 yrs. )

At 9 yrs. old the 'cups' are gone from all of the incisors but 'marks' are still evident although possibly absent altogether from the centrals. The 'dental star' is now apparent on the laterals as well as the centrals and about this age another hook develops on the upper corner incisor as a direct effect of wear. The central incisors are practically triangular in form ( 'rounded off' ) . Also making its first appearance around nine or ten years is a dark groove known as 'Galvayne's Groove' , on the outer surface of the upper corner incisor. The dark colouration is due to the presence of cement in the groove , while cement has worn off the rest of the tooth uncovering white enamel. The groove is found midway along the length of the tooth so that for some time after eruption it remains hidden in the socket. As the tooth grows out from the gum , the groove will gradually emerge. It first appears at the gum line and with continued eruption of the tooth it gradually extends down the length of the tooth.

At 10 yrs. the 'marks' are becoming indistinct but the 'dental stars' are more pronounced and are tending to round - off especially on the centrals.

The shape of the tooth - tables of centrals and laterals has now become noticeably more triangular ( 'rounded off' ) . Galvayne's groove is longer and both upper and lower incisors have begun to slop forwards.
