Anti-Wrinkle Injections in Kellyville
Subtle Facial Rejuvenation, Delivered with Clinical Care.

Botulinum Toxin Treatment for Facial Lines, TMJ and Bruxism
At Kellyville Smiles, we offer anti-wrinkle injections using Letybo, a Botulinum Toxin treatment designed to soften facial lines and help relax overactive muscles.
These treatments are commonly used for cosmetic facial rejuvenation, but they can also provide relief for conditions such as TMJ disorders and teeth grinding (bruxism).
Our approach is always conservative and personalised. The goal is to help you look refreshed while maintaining natural facial expression.
Botulinum Toxin
What Are Anti-Wrinkle Injections?
Anti-wrinkle injections use Botulinum Toxin to temporarily relax targeted muscles. When these muscles relax, the skin above them becomes smoother and fine lines or wrinkles soften.
The treatment is quick and minimally invasive, with most appointments completed in under 30 minutes.
Common areas treated include:
- Forehead lines
- Frown lines between the eyebrows
- Crow’s feet around the eyes
- Jaw muscles for teeth grinding
- Muscles contributing to TMJ discomfort

My daughters had an amazing experience! My younger one had her first check up and she actually enjoyed it and asked when she can come again. The dentist was very gently, lovely and did an amazing job with the clean. She also patiently answered all of questions. We will definitely be coming back.Posted on Google![]()

I recently removed 3 of my wisdom teeth here, the staff and Dr Peter himself are such a great team. Despite being very anxious beforehand i quickly became comfortable. During the extraction Dr Peter constantly asks if i was okay and comfortable and he was letting me know what i was going to feel (a little bit of pressure or vibrations) Honestly as someone who was very afraid of medical procedures i would 1000% recommend this practice to ANYONE.Posted on Google![]()

I had an excellent experience at Kellyville Smiles. I had my dental implant done here with Dr Peter, and I couldn’t be happier with the whole experience. Dr Peter was excellent very professional, caring and reassuring and all the admin staff were absolutely lovely and always made me feel welcome. I also had my teeth whitening and check up and Cleaning done here, and the whole process was great. They made sure I felt comfortable and relaxed throughout the treatment, and even put Netflix on for me, which was such a nice touch! I also was so happy with them when they try to fit me in as soon as possible for any emergency that happened to my teeth I highly recommend Kellyville Smiles.

Awesome people, very easy to talk to and amazing service!
Your appointment will begin with a consultation so we can discuss your concerns and determine whether treatment is appropriate.
During the procedure:
- The treatment areas are carefully assessed.
- Small amounts of Letybo are injected into specific muscles.
- The procedure usually takes around 15–30 minutes.
Most people can return to normal daily activities shortly after the appointment. Results typically begin to appear within a few days and gradually develop over the following weeks.

Treatment Options
Anti-Wrinkle Treatment Options
Anti-Wrinkle Treatment for Facial Lines
Facial expressions such as smiling, frowning and squinting can create lines in the skin over time. Anti-wrinkle injections help relax the muscles responsible for these movements.
This can help:
- soften existing expression lines
- prevent deeper wrinkle formation
- create a smoother, refreshed appearance
The aim is always subtle, natural-looking results rather than a “frozen” look.
Treatment for TMJ and Jaw Tension
Anti-wrinkle injections can also be used to help manage Temporomandibular Joint (TMJ) disorders.
When the jaw muscles are overactive, they can cause symptoms such as:
- jaw tension or soreness
- headaches
- difficulty opening or closing the mouth
- clicking or locking of the jaw
By relaxing specific jaw muscles, botulinum toxin treatment may help reduce the pressure placed on the TMJ and surrounding structures.
Treatment for Bruxism (Teeth Grinding)
Bruxism is the habit of clenching or grinding the teeth, often during sleep. Over time, this can lead to:
- worn or damaged teeth
- jaw pain
- headaches
- tight or enlarged jaw muscles
Botulinum toxin injections can help relax the muscles responsible for clenching, which may reduce the intensity of grinding and relieve muscle tension.
This treatment may be recommended alongside other approaches such as occlusal splints or night guards depending on your needs.

FREQUENTLY ASKED QUESTIONS
Have Any Questions?
How long do anti-wrinkle injections last?
Results from anti-wrinkle injections typically begin to appear within a few days and continue to improve over the following weeks. The effects usually last around 3–4 months, after which the treatment can be repeated if you wish to maintain the results.
Is anti-wrinkle treatment right for me?
Anti-wrinkle injections may be suitable for people who want to:
- soften facial expression lines
- prevent deeper wrinkle formation
- relieve jaw muscle tension
- reduce teeth grinding or clenching
- support TMJ treatment
A consultation is important to ensure the treatment is appropriate and safe for you.
What anti-wrinkle injections do you use at Kellyville Smiles?
At Kellyville Smiles we use Letybo, a Botulinum Toxin treatment used to soften facial lines and relax overactive muscles. It works in a similar way to other botulinum toxin treatments and can also support treatment for TMJ and teeth grinding (bruxism).
Can anti-wrinkle injections help with TMJ or teeth grinding?
Yes. Botulinum toxin injections can help relax the jaw muscles that contribute to TMJ discomfort and bruxism. By reducing muscle tension, treatment may help relieve jaw pain, headaches and clenching. A consultation is recommended to determine if this treatment is suitable for you.
