Nick Sheehan is Denplan Excel accredited. Denplan Excel is a certification programme focused on quality assurance, patient care and clear communication.
It supports our commitment to explaining your dental care clearly and maintaining high standards for our patients.
Denplan information for patients ↗Our practice has been based on Water Street in Carmarthen since 1999.
Nick Sheehan joined the practice in 2011 and has been Principal Dentist since 2015, bringing continuity and a personal approach to your care.
We believe prevention is the foundation of long-term oral health. We take time to explain your options and costs, so you can make informed decisions about your care.
Our practice offers general dentistry, hygiene care and cosmetic treatments, with digital scanning to support assessment and planning.
Clear treatment optionsPrevention firstFamilies welcomeMeet the team →Understand what each treatment involves before you take the next step. Your assessment helps us find the options that are right for you.
Keep everyday care at the heart of your smile. Regular examinations help us review your teeth, gums and oral health, while hygiene visits focus on cleaning and practical advice for home. Your dentist will recommend a visit interval based on your needs.
A filling repairs a tooth affected by decay or damage. We explain the options, the area being repaired and the estimated cost before treatment. The best choice depends on the tooth, the size of the repair and your bite.
A crown covers a tooth that needs additional support or restoration. A bridge can replace a missing tooth by using neighbouring teeth for support. We discuss materials, preparation, maintenance and alternatives at your assessment.
Root canal treatment cleans and seals the inside of a tooth when its pulp is inflamed or infected. We assess whether the tooth can be restored and explain the stages, likely costs and whether specialist care would be appropriate.
Replace missing teeth with a removable denture. Acrylic, flexible acrylic and chrome options are available. We help you understand comfort, appearance, support and ongoing care before deciding which option suits you.
Professional whitening can lighten the natural colour of your teeth. An assessment helps us check suitability and explain what to expect. Existing fillings, crowns and veneers do not whiten, so they may need separate consideration.
Tooth-coloured composite can change the shape or appearance of selected teeth. We discuss your goals, how much change is possible, ongoing maintenance and the alternatives before agreeing a treatment plan.
Veneers cover the front of selected teeth to change their appearance. They may involve tooth preparation and need maintenance over time. We discuss suitability and alternatives, including whitening or bonding where appropriate.
Clear removable aligners offer an option for straightening suitable smiles. Digital scanning and a ClinCheck plan help us assess the proposed movement. Wearing your aligners as directed and using retainers afterwards are essential.
For suitable patients, an appliance worn during sleep can help reduce snoring. We assess your teeth and bite, discuss your symptoms and explain whether a dental appliance may be appropriate.
If your breathing stops and starts during sleep, you wake gasping or choking, or you feel very sleepy during the day, speak to your GP about possible sleep apnoea before proceeding.
Grinding or clenching can cause tooth wear, sensitivity and jaw discomfort. Your dentist can assess your teeth and discuss whether a protective appliance or bite splint is suitable.
An appliance can help protect your teeth. It does not necessarily stop grinding or clenching, so we also discuss advice, possible contributing factors and ongoing review.
Fees shown are from the practice’s published 2026 guide. Your dentist will provide a personalised treatment plan and explain any additional costs.
Whether you are joining us for regular care, have a particular concern or are exploring a change to your smile, we begin by listening.

We explain findings, suitable options and fees. You can ask questions and agree the next steps with your dentist.
Our iTero digital scanner creates a detailed 3D view of your teeth to support assessment and treatment planning.
For suitable Invisalign cases, a digital ClinCheck plan shows the proposed tooth movements. We explain the aligners, any attachments or IPR that may be needed, and how retainers help maintain your result.
The published ClinCheck fee is £250, deducted from the Invisalign treatment fee if you proceed. Published treatment fees are £3,000 for a single arch and £4,000 for both arches; retainers are priced separately.
Treatment suitability, duration and outcome vary. Your dentist will explain your individual plan and whether a specialist opinion is appropriate.
We explain fees before treatment and provide a plan tailored to your needs. Our published fee guide helps you understand the starting point.
Denplan Care and Denplan Essentials offer ways to spread the cost of dental care. Ask reception about suitability, monthly fees, benefits and exclusions before choosing a plan.
