Definitions


Normal Dentition

 Decreased/lack of lateral movement: When we examine your horse, one of the first things we do is check for lateral (side to side) movement. Sharp points, missing teeth, abnormal occlusion and TMJ issues call all affect this.

 

Sharp points: These are the outside edges of the teeth (cheek side of the upper teeth, tongue side of the lower).

 

Buccal ulcers: Wounds on the cheeks, usually from sharp points. These usually heal within 1 week of a dental equilibration (float).

 

Lingual ulcers: Wounds on the tongue, usually from sharp points. Again, these usually heal within 1 week of floating.

 

Periodontal pocket: A detachment of the periodontal ligament from the tooth often resulting in a pocket where food can become lodged.

 

Diastema: This is a gap between the teeth that often fills with feed material and causes further inflammation of the periodontium.

 

Wave: When more than 1 tooth in a row that has excess crown.

 

Step: Only 1 tooth has an excessive crown.

 

Ridge: When only a part of the tooth is has an excess of crown, but does not fit into the other categories. This is usually seen on the transverse ridges (outside edge) of the tooth.

 

Ramp: This is a tooth that has excess crown which is wider than it is tall. It looks like a ramp.

 

Hook: This is just as it sounds; it is used to describe a tooth that has an excess crown that is taller than it is wide.

 

Infundibular necrosis: This is the horse equivalent to a cavity.

 

Cupping: This term is used to describe a tooth that has been worn down past the infundibulum. The appearance is like that of a cup.

 

Infundibulum: This is part of the tooth that is funnel shaped (wider at the top) that is filled with cementum and surrounded by enamel.

 

Expired teeth: Teeth that have worn down to the gingival margin. These teeth are no longer able to be used in grinding.
