Simply deduct this from the gross figure. I am assuming a vat rate of 17.5%. I have tried to show the underlying methodology, because if the vat rate changes you won't understand how to re-calculate. If the vat rate was 20% you would multiply the gross by 20 and divide by 120.
It is now known that the cause of tooth abfraction can directly be linked to clenching and grinding of teeth. This can occur during the day but most of the time it occurs at nighttime when youâre asleep.
It come from a frequent rubbing or scraping against the tooth surface, that over time results in the loss of some tooth tissue. This is caused in most cases by our trusted friend the tooth brush being used over zealously.
