Bad breath is a very common problem and there are many different causes. Some people find that they have bad breath all the time and there may be an underlying medical cause for that, such as throat, nose or lung infections and sinusitis, bronchitis or diabetes.
You can also suffer from bad breath if you have poor dental hygiene. Without regular brushing and flossing, bacteria and bits of food can get trapped in between your teeth, which release an unpleasant odour after some time. Another cause of bad breath is smoking. Bad breath is also caused or made worse by strong foods like garlic, onions and coffee.
Bad breath can be prevented by following a daily oral hygiene regime and cutting down on sugary foods and drinks. Regular trips to the hygienist will also ensure your plaque levels are kept under control.
EXCELLENT Based on 82 reviews Posted on Anita Hair2026-02-26Trustindex verifies that the original source of the review is Google. I’ve had an excellent experience with Costin and Pam at Portland Street Dentist. I decided to get braces just before turning 30, and it’s honestly one of the best decisions I’ve ever made. My teeth are now so straight, and I couldn’t be happier with the results. I was quite nervous at the start and told Costin that I really don’t like dentists or pain, but every single appointment was handled with such care and gentleness. They always made me feel comfortable and reassured throughout the whole process. I would absolutely recommend Portland Street Dentist to anyone considering braces especially if you’re feeling a little anxious like I was! I have also had other dental treatment here, and has been great service every time.Posted on Lewis Ball2026-02-05Trustindex verifies that the original source of the review is Google. I honestly can’t recommend this dentist highly enough! I had Spark orthodontic treatment and the results are absolutely fantastic. My face aches from smiling so much! 😁 Pam and Costin have been incredibly welcoming from the start and the level of care they provide is exceptional. They made every appointment comfortable, reassuring, and kept me informed throughout. I now wouldn’t want to go anywhere else! Thank you both again for such brilliant results!Posted on Jade Mori2025-08-22Trustindex verifies that the original source of the review is Google. Pamela and Costin made me feel welcome and relaxed throughout the process of my dental work. All of my options were explained with pros and cons, and they went the extra mile to ensure that I would leave happy with my new smile (which I really did!). Costin is a perfectionist!Posted on Καλλιόπη Κασάπογλου2025-07-02Trustindex verifies that the original source of the review is Google.

As a nervous patient, Pamela and Costin made me feel at ease from the very beginning. I had a root canal filling, two smaller fillings and a clean. I can honestly say that it's been the best dental experience I've ever had. I would recommend them to anyone.Posted on paula caplen2025-05-29Trustindex verifies that the original source of the review is Google.

Great experience, very personal, welcoming, caring and calming. Highly recommend.Posted on Corina Vasile2024-12-18Trustindex verifies that the original source of the review is Google. My experience with the practice and both Costin and Pamela was absolutely great because I felt safe, really looked after, treated with respect and kindness at all times. This is that type of place where you feel you are at the centre of their efforts and the price is a fair one compared to so many other places. Pamela and Costin worked with me for aprox 3 years now. I first had a crown made and then braces and the result of both is just amazing. Nothing was too much for them and they went beyond and above with their care and assistance so I can enjoy smiling again. Thank you both for a really meaningful experience with an outstanding result😘Posted on Nvk K.n.v2024-10-21Trustindex verifies that the original source of the review is Google.
