This has been my dental surgery for years, the staff are welcoming and honest with their work. I was living elsewhere and had a check up that suggested i get 3 fillings and 3 teeth removed I never went through with it and when i returned and make an appointment I was assured that my teeth were fine and not to be messed with :D Would recommend to anyone looking for a good private dentist


I had my first appointment today, an emergency one, and cannot thank them enough. To begin with I sent an email in the morning before they opened and the receptionist that phoned me back at 9am was lovely and so kind. I had an appointment before 10am. Sherrie the dentist was patient and so understanding. She explained all of my options and I was back in the chair that afternoon for treatment. Both receptionists were amazing in person and I cannot fault this practice in the slightest.
Been a patient with Smiles Ahead got many years now and can honestly say the care has been exemplary. The staff are always professional and friendly and will go above and beyond for you if need be. They deserve all the accolades they have received. Thank you all.
The treatment I received was excellent. As the patient you are given a full and thorough examination, and everything is explained step by step. All the staff make you feel at ease. Highly recommende the practice.

Invisalign uses a series of clear, removable aligners that are custom-made to fit your teeth. Each set gently shifts your teeth little by little until they’re in their ideal position. You’ll typically wear each aligner for 1–2 weeks before moving on to the next one.
Most people find Invisalign much more comfortable than traditional braces. You may feel a bit of pressure or tightness when switching to a new set of aligners, but this usually fades after a day or two.
Your treatment time will depend on your needs, so it varies from person to person. Once you’ve had your consultation, your dentist can give you a personalised timeline, but it’s usually between 9 and 18 months.
You should remove your aligners before eating or drinking anything other than water. This helps avoid staining and keeps your aligners in great shape. That means no food restrictions during your treatment, so you can enjoy all your favourites without worry.
For the best results, you should wear your Invisalign aligners for 20–22 hours a day. That means keeping them in while you sleep and only taking them out to eat, drink, brush, or floss.
