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.
Chronic snorting of cocaine and use of methamphetamines can cause abnormal changes in enamel. Swimmers who spend a lot of time in overchlorinated pools can lose tooth enamel, as can people who work with acids. Excess fluoride ingestion (fluorosis) during childhood can cause mottling of the enamel. Damaged tooth enamel can allow bacteria to more easily invade the tooth and form a cavity.
