Spalling & Pitting
Worn teeth:
Permissible wear is as a rule 1/3 of the thickness of the upper part of a tooth, provided that
• the wear is uniform over the whole of the flank of a tooth
• and all teeth are worn in the same way.
Spalling:
Small bits of the teeth have broken off, so-called spalling. This is generally due to excessive load or improper lubrication. Damage of this type need not necessitate immediate replacement, but careful checking at short intervals is imperative.
Pitting:
Small cavities in the teeth, so-called pitting, can occur through excessive load or improper lubrication. Damage of this type need not necessitate immediate replacement, but careful check at short intervals is imperative.
