UK’s top dentists were asked about the latest treatments that are being adopted to relieve people of teeth and gum problems.

The ­Dental Institute at Barts and the London School of ­Medicine and Dentistry has patented toothpaste that protects your teeth by using dissolvable glass ­particles.

Calcium and fluoride is released that strengthens teeth by the microscopic particles that stick to your teeth and dissolve. Teeth sensitivity is also reduced.

Professor Robert Hill, professor of physical sciences at St Bartholomew’s Hospital in London, said, “You brush your teeth with it twice a day, like normal. It releases minerals over 24 hours, which stay in the mouth for longer. We’re aiming for it to cost £3 a tube.”

An inhalable dental anaesthetic has been made by scientists that numbs your top teeth for 30 to 90 minutes. It gets collected in large portions in teeth, jaw and structures of the mouth by travelling through the main nerve in the face as upper jaw bone has more holes as it is more porous.

Dr Uchenna Okoye, of ­dental practice ­Londonsmiling. com, said, “90 per cent of patients suffer more pain from the injection in their gums than the tooth that was worked on. This is a great breakthrough for all ­needle-phobics.”

Trials for a spray or nasal drops are being carried out by U. S. pharmaceutical firm St Renatus.

Attempts to treat periodontal diseases are being made by Cardiff University scientists by using them.
