I have had profile balancing with Tara and I can honestly say it's been life changing. I no longer hesitate to do anything, I do not think about hiding my face when I smile or laugh or from the side. I only wish I had had the treatment done long ago. The new clinic is beautiful 😍 Tara is amazing she puts you at ease there is no pressure to treat and explains everything treatment is virtually pain free and only the teeniest of bruising. Emma on reception is wonderful very welcoming and makes you feel relaxed. I can not wait to get a few more tweaks.

I visited Tara and the clinic for my first time at ever having dermal filler. Tara is absolutely amazing at what she does, she made me feel so unbelievably comfortable and my results are so naturally amazing. She has really boosted my confidence and I knew I was in such safe hands. I cant wait to see her again in a few months time, and I also cant wait to visit the clinic for additional services. The clinic is absolutely amazing and as soon as you step in side, you feel so welcome. I cant thank her enough! I couldn't of wished for more, she is an absolute perfectionist at what she does and I am so grateful for finding her.

Dr. Tara and the team have always taken very good care of me. She has always been very attentive to my concerns and made me feel at ease during and after all my treatments. It can be daunting to go through with fillers but she has always made me feel safe & is very skilled at what she does. She is always there to provide help and advice post-treatment too, should you have any concerns. Her dedication to her craft and her patients shows through her work and the amazing service she provides. Thank you so much for all that you’ve done for me Tara, couldn’t recommend highly enough!x

Teeth Whitening Treatment Journey

Your Implant Retained Dentures treatment will be tailored to your exact requirements; therefore, one treatment can be very different from the next. However, we’ve provided a basic overview of a Implant Retained Dentures below.

First step


During the consultation, our dentist will assess your oral health, discuss your goals, and determine your candidacy for Teeth Whitening. We will address any concerns and provide recommendations based on your unique situation.

second step


Before the Teeth Whitening procedure, a thorough dental cleaning may be performed to remove any plaque or tartar. This ensures optimal results by allowing the whitening gel to come into direct contact with the tooth surface.

third step


A protective barrier is applied to your gums, and a professional-grade whitening gel is carefully applied to your teeth. This gel contains a safe concentration of hydrogen peroxide or carbamide peroxide, which breaks down the stains on your teeth. The gel is activated using a special light or laser for an accelerated whitening effect.

When you are done


Avoid consuming staining substances such as coffee, tea, red wine, or tobacco for at least 48 hours.
Maintain good oral hygiene by brushing your teeth twice a day and flossing daily to prevent new stains from forming.

Meet The Dental Team


I have now visited Twoth on three different occasion... The first time was to take my son (8 years old) to see Dr Counihan for a braces consultation and my son absolutely loved the entire experience from start to finish. In fact, he was so excited and relaxed about it all he wanted to get started immediately.

The second time around, I went to see Dr Counihan myself for a second opinion and found the experience just as good as my son did

Karin Thyselius

Before I found Dr Neil Counihan I had a long history of dental trauma and sadly I repeatedly was subjected to very poor dentistry. I was scared to let anybody near my mouth and teeth. I had lost hope!

Dr Counihan made me the promise, with the right care I can keep my mouth healthy and definitely keep my teeth for the rest of my life.

And most importantly he made me feel safe and listened to

Frequently Asked Questions

Find the answer to the most common questions. Everything you need to know about Teeth Whitening

Yes, Teeth Whitening performed by dental professionals is safe. Our clinic uses professional-grade products and techniques to ensure both safety and efficacy.

The duration of Teeth Whitening treatment can vary depending on the individual and the desired results. In most cases, the procedure takes about 1 to 2 hours.

Some patients may experience temporary tooth sensitivity during or after the treatment, but it typically subsides within a few days. We take steps to minimize sensitivity and ensure your comfort.

The longevity of Teeth Whitening results varies among individuals and depends on lifestyle habits. With proper care and maintenance, the results can last up to a year or longer.

Teeth Whitening is effective in removing extrinsic stains caused by food, beverages, and tobacco. However, it may not be as effective on intrinsic stains that originate from within the tooth.

Teeth Whitening treatments primarily work on natural teeth and may not lighten the color of dental restorations. If you have visible restorations, your dentist can provide alternative options to improve their appearance.

Teeth Whitening is generally safe for individuals of various ages. However, it is not typically recommended for children under the age of 16 or for pregnant or breastfeeding women.

While over-the-counter whitening products are available, professional Teeth Whitening performed by a dentist ensures safer and more effective results.

The results of Teeth Whitening treatment are immediate, and you will notice a significant improvement in the color of your teeth right after the procedure.

In most cases, Teeth Whitening is considered a cosmetic procedure and is not typically covered by dental insurance. It’s best to check with your insurance provider to determine coverage details.
