Actress Nadia Sawalha has revealed that she has regular Botox injections to protect her smile. Speaking on TV show Loose Women, she explained that without Botox she runs the risk of losing her teeth.

“I have Botox in my teeth to stop them grinding. It’s because I’m losing my teeth from grinding them,” she said on the debate show.

She is far from the only person who suffers from Bruxism – the term for unconscious teeth clenching – to receive Botox as a treatment. Injections of the muscle-relaxing toxin are increasingly being used to help people who consistently grind their teeth.

Having Botox in your teeth to help treat teeth grinding may seem like an odd use for a procedure better known as a way of reducing the appearance of wrinkles on the skin.

However, Botox is being used to treat an increasing number of conditions, from headaches to depression.

The Daily Mail recently revealed that Botox is now being used to treat arthritis in the shoulder by some surgeons in the UK.

According to the newspaper, a single injection has been enough for some patients to be pain-free when suffering from rotator cuff arthropathy. Tears in the tissue around the shoulder are caused by the shoulder blades rubbing against the tendons as they weaken – a common situation in those over the age of 60.

The reason Botox helps the condition is because it works on the damaged muscle. Speaking to the news provider, consultant shoulder and elbow surgeon at the Royal Devon and Exeter Hospital Chris Smith explained: “Injecting Botox stops that muscle from moving. As it is unable to contract, it is hoped that this removes the strain from any remaining partially torn tendon.”

He added that it could potentially save the NHS a significant amount of money, because Botox treatments are 50 times cheaper than a joint replacement, which is another option for treating this kind of condition.

Shoulder injuries and teeth grinding aren’t the only new applications for Botox that have emerged recently.

Researchers have also been looking into whether injections of botulinum toxin can be used to help treat depression.

A team in the US are exploring the possibility that preventing the muscle between the eyebrows from working, where emotions such as sadness, anger and fear are expressed, could make it harder to experience such negative emotions.

This is one of several trials that have been conducted looking at whether Botox injections can help those who suffer from mental health conditions like depression.

With more and more medical uses of Botox coming to light, it’s likely that there will be a growing number of conditions that can be helped by these injections in future. If you’re intending to take Botox advanced courses, you could find that your skills can help in more ways than just to give people a boost in their bid to look younger.

Of course, there is still strong demand for Botox from those looking to roll back the years and regain their youthful appearance, as well as a growing number of younger people who are opting for Botox to help prevent wrinkles from forming in the first place.
