Stress:
One of the most common causes of teeth grinding is stress. When individuals are under high levels of stress they may clench their jaw muscles tightly without even realising it. This leads to them unknowingly grinding their teeth together throughout the day or night.
Medications:
Some medications have been linked to increased instances of teeth grinding due to side effects such as drowsiness and muscle relaxation that make it easier for people to do so unconsciously.
Sleep Disorders:
People who suffer from sleep disorders such as insomnia or sleep apnea often experience episodes of involuntary tooth clenching and/or grinding during the night when they are not fully conscious.
Treatment for teeth grinding
One treatment option that Dr Paulina recommends for teeth grinding at her clinic in Sevenoaks is botox injections which have been found to be highly effective in reducing or eliminating teeth grinding altogether. 
Botulinum toxin (botox) has been used successfully since 1997 to treat patients suffering from bruxism due to its ability to relax facial muscles around the mouth area where most people grind their teeth at night while sleeping.
The injection works by blocking nerve signals that control muscle movement so that they cannot contract involuntarily causing you to clench your jaws together tightly throughout the night without realising it until morning when you wake up with an aching jawline! 
What are the benefits of using Botox for treating teeth grinding?
Quick Relief:
Unlike other forms of treatment for bruxism or teeth grinding which may take weeks or months before any relief is felt; botulinum toxin (botox) injections provide almost immediate relief from painful symptoms caused by excessive teeth clenching and teeth grinding habits within just 24 hours after administration! This makes them ideal for those who need fast results but don’t want long term solutions like orthodontic appliances etc..
Long Lasting Results:
Another benefit of using botox injections instead of traditional methods like dental splints or crowns is that it provides longer lasting effects than these alternatives do - usually lasting anywhere between 3-6 months depending on how severe your case was initially and how well you respond positively towards regular maintenance sessions every few months afterwards.
Non Invasive Treatment Option:
Finally another great advantage about opting for this type of therapy rather than more invasive options like surgery etc., would be its non-invasive nature meaning no cutting into gums/teeth required whatsoever making it much safer overall compared with some other procedures out there today.
Using botulinum toxin (botox) injections as a form of treatment for bruxism or teeth grinding at Dr Paulina's clinic in Sevenoaks offers many advantages including quick relief from painful symptoms associated with excessive clenching and teeth grinding habits; long lasting results; and being non-invasive in nature making it much safer overall compared with some other procedures out there today.
