Are you looking to achieve your perfect smile without braces? Invisalign is the modern way to get the beautiful straight teeth you’ve always wanted — without braces.
At Smith Street Dental in Penrith, Dr Peter Sidhom is our experienced Invisalign dentist. He has thoroughly embraced the new Invisalign technology to help you and your family achieve the perfect smile. With over 10 years of experience with Invisalign, Dr Sidhom was one of the first dentists to implement it in the Penrith community.

About Invisalign
Invisalign uses a series of invisible, removable, and comfortable aligners that no one can tell you’re wearing. So, you can smile more during treatment as well as after. Invisalign is made with 3-D computer imaging technology and has been proven highly effective and accurate, especially for adults.
What is it? Invisalign® Aligners use a series of invisible, removable, and comfortable aligner trays made with 3D computer imaging technology. Each set is worn for approximately two weeks, with check-in appointments around every six weeks. Total program wear typically ranges from 18 to 30 trays, with overall duration varying by case.
Who is it for? Adults and families seeking a discreet alternative to braces to straighten their teeth without metal or wires.
How Invisalign Works
You’ll wear each set of aligners for about two weeks, removing them only to eat, drink, brush, and floss. As you replace each aligner with the next in the series, your teeth will gradually move into the final position prescribed. You’ll need an appointment about once every six weeks to ensure your treatment is progressing as planned. Total treatment time averages 9-15 months, and the average number of aligners worn is between 18 and 30, but both will vary from case to case.
Benefits of Invisalign
- Invisible aligners blend seamlessly with your teeth
- Removable for eating, drinking, brushing, and flossing
- Comfortable, with no metal to cause mouth abrasions
- Fewer in-office visits for adjustments
- Virtual treatment plan to preview your future smile
