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

What Is Root Canal ?

At our clinic, we offer professional and compassionate dental root canal treatment to restore the health and functionality of your teeth. Root canal treatment is a procedure designed to address the innermost layers of the tooth, where the dental pulp and nerves are located. This treatment becomes necessary when these vital components become infected or damaged due to deep decay, cracks, or trauma.
During the procedure, our experienced dental team carefully removes the infected or damaged pulp, cleans the area, and seals it with a biocompatible material. This process not only relieves your pain and discomfort but also helps to save your natural tooth, eliminating the need for extraction. By preserving your tooth, root canal treatment restores its strength, stability, and appearance, allowing you to chew, speak, and smile with confidence.

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
