Welcoming New Patients today

We believe in transparency and value. Our new patient appointments are designed to give you a comprehensive understanding of your oral health, with no pressure, and plenty of time to ask questions. 

Our adult new patient exam is £100 and includes a FREE Hygiene SPA experience worth £115

Your first appointment includes:

  • Screening radiographs: This allow us to reveal any hidden dental problems, review past dental work and forms a foundation for your treatment plan.
  • OPG radiograph (if clinically required): This gives us a panoramic view, and offers more diagnostic value for problem areas.
  • Itero digital scan: A non-invasive, radiation-free way to capture a highly detailed 3D image of your teeth, gums, and bite. We use this as part of a comprehensive initial assessment, especially when planning cosmetic, restorative, or orthodontic treatments.
  • Oral cancer screening: This is a non-invasive, quick, and painless process, typically taking just a few minutes.
  • Periodontal health screening: Assesses the health of the gums and supporting structures of the teeth.

“The team here are incredibly helpful and kind. From the receptionist who always greets you with a smile and a chat to the dentists. I always feel cared for” (August 2025)

Invisalign Aligners For Your Children

Invisalign® First is a popular choice for kids because it is nearly invisible and very comfortable to wear.

It works by gradually moving your child’s teeth into the proper position using a series of clear, custom-made aligners.

In most cases, treatment will take between 6 and 12 months. We use Dental monitoring and see children every 3 months on average so that we can assess their progress and make any necessary adjustments.

You will need a complimentary smile evaluation to know if your child is a candidate for Invisalign® First. Feel free to request one today!

17th April 2026

I was running late for my appointment due to train cancellation, phoned ahead to let reception know and my lateness was accommodated. I was met with smiles from the whole team and was treated with courtesy throughout my appointment.

12th April 2026

Mr Hampton is always professional and cleans my teeth excellently, offering advice on the problems I am having with arthritis. I feel that he cares for my implants particularly well.

30th March 2026

Everything mentioned in the survey was great, but I felt weirded out afterwards about signing forms consenting to have my pictures used on social media. It happened so fast that I neglected to ask what happens if I don't consent, and I neglected to get printed copies of the documents I signed. I don't object to my pictures being used for clinical or research purposes but I don't want them on social media. If I could revoke my consent I would.

30th March 2026

Rory clearly explained everything to me and did his best to make the treatment as comfortable as possible.

29th March 2026

I have been attending this practice for several years, and it would not occur to me to go anywhere else. This is an excellent practice, and long may it continue.

28th March 2026

I always book my hygienist appointments with Mr Hammond. He’s professional, punctual, reliable, polite, methodical, thorough and informative.

23rd March 2026

Excellent hygeinist Jessica put me at ease spent time discussing my mouth hygeine and ways I could improve it, gentle and kind.

Invisalign®

We offer Invisalign treatments for children and Teenagers if desired and appropriate for specific treatment. 

The British Orthodontic Society recommends an initial orthodontic assessment at around the age of 7. However, the right age for treatment varies depending on the individual child’s needs.

Orthodontic treatment can address a variety of issues, including crooked teeth, overcrowding, misalignment, overbite, underbite, and issues with jaw development.

The duration of treatment varies depending on the complexity of the case. On average, treatment may last between 12 and 24 months.

Traditional metal braces, ceramic braces, and invisible aligners (such as Invisalign) are commonly used. The appropriate type depends on the child’s specific needs and the orthodontist’s recommendation.

Initially, there may be some discomfort or soreness when braces are first applied or adjusted. Over-the-counter pain relievers can help manage this discomfort. At H Williams & associates we provide regular appointments making minor adjustments rather that infrequent major adjustments.

Yes, but it’s important to wear a mouthguard during sports to protect the braces. Playing musical instruments may require an adjustment period.

The orthodontist will provide specific instructions, but generally, good oral hygiene practices, including regular brushing and flossing, are essential. Special care may be needed for certain types of braces.

Additional information about Children’s Orthodontics

What is orthodontics? 

Orthodontics is the movement of the teeth within the jaw bones to straighten them and help them to bite more evenly together. Orthodontic treatment is about making the best of your teeth; it’s about improving the harmony of your mouth and jaws.

What is a specialist orthodontist? 

Orthodontists firstly become fully qualified dentists before completing a further period of training and examinations in order to specialise in orthodontics. A specialist orthodontist will have carried out at least 3 years extra training after becoming a qualified dentist. Only those dentists who have completed this training can register with GDC (General Dental Council) as a specialist orthodontist. 

 

Who needs orthodontist treatment?

Most children begin treatment around the age of 12 or 13, once all their permanent teeth have erupted. In a few instances treatment is better started early and your dentist may want to make an earlier referral. But age is not a barrier to treatment and the number of adults seeking treatments is on the increase. 

Orthodontic treatment is recommended for individuals who have various dental and jaw alignment issues. These issues can range from common misalignments like overbites, underbites, and crowding to more complex problems involving jaw positioning. People with malocclusions that affect their bite, such as open bites or crossbites, may also require orthodontic care. 

Additionally, individuals with aesthetic concerns about the appearance of their teeth may seek orthodontic treatment for cosmetic reasons. Ultimately, the decision to undergo orthodontic treatment is determined through evaluation by an orthodontist, who assesses the specific dental and orthodontic needs of each patient and recommends an appropriate treatment plan, which may include braces, clear aligners, or other orthodontic appliances.
