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 Invisalign ?

You’ve probably heard of Invisalign, but what exactly is it? In short, it’s a discreet and pain-free way to solve the problems of crowded or uneven teeth. There’s no need for the traditional train-track braces, which are effective but also very noticeable. With Invisalign, you’ll get a clear tray that fits seamlessly over your teeth, coaxing them into position over a period of months.

Invisalign works in a simple yet ingenious way, aligning your teeth gradually. Your dentist will initially fit you with your translucent tray, which snaps over your teeth and then place small amounts of pressure on specific areas of your mouth. This light pressure slowly moves your teeth into their desired positions.


From £490 per syringe (depending on practitioner).

Benefits of Invisalign

There are several benefits to Dental Implants, which is why it’s such a popular option with many patients in our London practice. We’ve gone over just a few of the Dental Implants benefits below.

Gain a Stunning Smile

Invisalign is a superb way to get the smile you’ve always wanted. You’ll start seeing results almost immediately, and you can hit your end goal within just a few months.

Exceptional Comfort

Invisalign is the most comfortable way to align teeth, thanks to the lack of wires and braces. Moreover, there’s no need to spend ages in the dentist’s chair while braces are fitted.

Nearly Invisible

If you’re conscious of your appearance, fixed braces might not be the choice for you. Instead, pick Invisalign, as the aligners are nearly invisible.

Conveniently Removable

Invisalign trays can be removed whenever you need to, including when you eat, brush, and floss your teeth. However, they must be worn for at least 20 hours a day.

Your Invisalign 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 Invisalign below.

First step


During the consultation, our Invisalign specialist will assess your dental condition, discuss your treatment goals, and determine if Invisalign is the right option for you.
We may take digital impressions, X-rays, and photographs to create a precise treatment plan

second step


If necessary, any existing dental issues, such as cavities or gum disease, will be addressed before starting Invisalign treatment.
A customized treatment plan will be created, outlining the specific movements of your teeth and the estimated duration of the treatment.

third step


You will receive a series of clear aligners, each to be worn for approximately two weeks, gradually moving your teeth towards the desired position.
Regular check-ups will be scheduled every 4-6 weeks to monitor progress and provide you with new sets of aligners.

When you are done


Wear your aligners for 20-22 hours a day, removing them only when eating, drinking, brushing, and flossing.
Clean your aligners regularly by gently brushing them with a toothbrush and rinsing them with lukewarm water to prevent plaque buildup.

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 Invisalign

The length of the treatment depends on how complex your case is. However, the average time it takes for Invisalign to straighten teeth is 12-18 months – a much shorter period of time than when using fixed braces.

While the Invisalign treatment can take a while, you will be able to see the difference after just a few weeks, which provides the motivation needed to continue with your Invisalign

Invisalign cost depends on the complexity of your requirements – the more complex, the more the treatment will cost. However, you should typically budget approximately [ENTER PRICE RANGE] for Invisalign in London with Twoth.

We offer payment plans for those looking to spread the cost of their Invisalign treatment over a set time. A team member can talk you through the price for your treatment and payment options when you visit for your first consultation. Please note that getting free Invisalign via the NHS is not possible.

Invisalign works in a simple yet highly effective way. Clear aligners gently apply pressure to specific teeth, moving them slowly into new positions. A new aligner is used each week, ensuring they fit and work perfectly with your mouth.

Once the Invisalign treatment has been finished, you must wear a retainer. This prevents your newly aligned teeth from reverting to their previous positions. Like the aligners, your retainer will also be almost invisible.

There are rarely any side effects from using Invisalign, but some people experience slight discomfort, especially when using their aligners for the first time. Some also experience a dry mouth, plus weight loss is possible, as many people eat less when wearing their aligners.

If you have any concerns about side effects from your Invisalign aligners, you should speak to your Twoth dentist as soon as possible. They will then be able to advise on how to progress with the treatment.

For most people, Invisalign is exceptionally comfortable, although it might take a few days to become used to the aligners in your mouth. You’ll also experience no discomfort when your dentist fits the aligners.

While comfortable, you will initially feel small amounts of pressure against your teeth, disappearing as you become accustomed to the sensation. If you experience prolonged discomfort or pain, contact us as soon as possible.

Both Invisalign and fixed braces are exceptionally effective. However, Invisalign is best used for less severe issues, most notably crowding, while fixed braces are best used to remedy more complex cases.

However, in terms of aesthetics, most people agree that Invisalign is superior, as the aligners are almost invisible. Cost-wise, both treatments are generally about the same, although you will need to discuss this with a team member at Twoth.

Yes, all Invisalign users will need a retainer afterwards, designed and manufactured to fit your mouth perfectly. They are also exceptionally discreet, just like your Invisalign aligners, plus they feel comfortable to wear.

Retainers need to be worn to give your body enough time to build new bone structure to stabilise your teeth in their new positions. This usually takes 9-12 months. Your dentist will tell you when you can stop wearing a retainer.

Brushing your teeth is exceptionally simple with Invisalign, as you just remove your aligners and brush as usual. If you have had any elastics, buttons, or bite ramps fitted, just brush around them. If you’re unsure, your dentist or hygienist can talk you through your brushing and flossing routine.

It is also important to claim your aligners regularly, as well as your teeth. You can clean your aligner using your toothbrush and toothpaste. Do not use hot water, as this could alter the aligner’s shape, making it less effective.
