It is always better to prevent a cavity from occurring as opposed to actively treating damaged teeth and gums after the fact. This is why your dentist will normally perform several preventative steps.
What are three important actions which might be taken?
– Dentist will clean and polish your teeth during a visit.
– Enamel-protecting substances such as fluoride may be applied.
– You will be given oral hygiene and dietary advice.
”There are now many specialised toothpastes, including total care toothpastes and toothpastes made specially to help with plaque, gum disease and sensitive teeth.”
