Our services

Restorative Dentistry

Restorative dentistry is concerned with preserving and restoring oral health by means of the study, diagnosis and management of dental disease.

The primary focus of the restorative department at York Hospital is to provide specialist oral rehabilitation to restore function and aesthetics for patients with congenital and acquired dento-facial defects.

The specialty includes all of the activities associated with the subspecialties of Implantology (Dental implants), Prosthodontics (crowns, bridges, dentures), Endodontics (root fillings) and Periodontics (gum disease).

Another major role of the Consultant in Restorative Dentistry is to provide an advisory service for general dental practitioners and their patients.

What services do we provide?

  • A diagnostic and treatment planning service for a wide range of congenital and acquired diseases and disorders affecting the mouth, face and jaws
  • Diagnosis, assessment and specialist advice for treatment to the referring dental practitioner
  • A number of patients will be accepted for treatment should they fall within the defined acceptance criteria for specialist hospital care

Who can refer?

  • General dental practitioners
  • High street specialists in the dental disciplines
  • Generally we would not expect referrals directly from general medical practitioners

Referral criteria for consultation

Your Dentist may refer if you require:

  • A specialist opinion
  • Assessment, diagnosis, and advice
  • Treatment planning for the referring practitioner

Treatment acceptance criteria

The remit of the Restorative service at York Hospital is to provide oral rehabilitation for:

  • Head and neck oncology patients that have significantly altered anatomy, high risk of osteoradionecrosis (ORN) and complex functional aesthetics requiring multidisciplinary care
  • Congenital and acquired defects requiring specialist skills to restore function and aesthetics
  • Severe congenital abnormalities in tooth number, form or structure (hypodontia, palatal cleft, amelogenesis and dentinogenesis imperfecta) where the treatment is beyond the scope of the primary dental care services
  • Trauma resulting in significant acquired defects or requiring implant restoration and multidisciplinary secondary care

If accepted for treatment we aim to work with the referring dental practitioner and would ask that they provide routine dental care. Due to limited resources ongoing support and maintenance care will be expected to be provided in the primary or community care services.

Dentistry implants

A number of dental implants are available under the NHS and only in the categories listed below:

  • Acquired defects as a result of ablative surgery for head and neck cancer
  • Congenital defects e.g. hypodontia, cleft lip and palate
  • Tooth tissue loss following trauma
  • Please note: Patients in whom tooth loss occurred due to trauma more than two years ago may not necessarily qualify for NHS implants.
  • Continuing problems with well made and fitting complete dentures (as deemed by a Consultant in Restorative Dentistry).

Service summary

The Restorative Consultant's treatment remit is to provide oral rehabilitation for patients that require multidisciplinary care along with colleagues in the Head and Neck cancer team, the Maxillofacial department and Orthodontic Department. For this reason treatment is limited to high priority groups (Head & Neck Oncology, Trauma, or Congenital abnormalities) with complex oral health problems.

The restorative department in York Hospital provides an advisory service for general dental practitioner's requesting a specialist second opinion and for treatment planning. We will accept any patient for assessment, second opinion or treatment planning referred within the NHS.

Visiting cancelled

Due to the increasing number of cases of coronavirus across the UK, York Teaching Hospital NHS Foundation Trust has made the decision to cancel all visiting to all its hospital sites in order to ensure the safety of patients and staff.

There are three exemptions to the ruling which are for one parent of a sick child under 18, for the partner of a woman giving birth and end of life patients at the discretion of the ward sister.

We would ask people to respect this decision and to treat our staff, who will be enforcing the visiting restrictions, with courtesy and respect.  For more information visit our website.

Outpatient appointments

We know that NHS services will come under intense pressure as the coronavirus spreads, and as a Trust we need to redirect staff, free up staff for refresher training and carry out any works as necessary, so we are able to maximise capacity for patients for when the number of infections peak.  We also need to reduce the number of people coming into our hospitals to protect our patients, as well as keeping our staff safe, well and able to come into work.

To do this, with effect from Tuesday 24 March 2020, along with other trusts in the Humber Coast and Vale partnerships, we have made the collective decision to suspend all non-urgent routine outpatient appointments for at least three months.  Urgent and emergency cases and cancer appointments will be carrying on as normal.

These are unprecedented times and we thank you for your understanding.  We know many people waiting for treatment will be disappointed or worried but please not contact the hospital as we will be contacting everyone directly affected in the coming days and weeks.

If you do not receive a letter or a phone call from the hospital, please turn up for your scheduled appointment as normal unless you have symptoms of coronavirus, a cold, flu or norovirus in which case you should contact us to cancel your appointment by clicking here.

Coronavirus (COVID-19)

If you have symptoms associated with coronavirus including a new continuous cough and a high temperature, you are advised to stay at home for 7 days.

Please do not book a GP appointment or attend your GP practice.

If you live with other people, they should stay at home for at least 14 days, to avoid spreading the infection outside the home.  After 14 days, anyone you live with who does not have symptoms can return to their normal routine.

But, if anyone in your home gets symptoms, they should stay at home for 7 days from the day their symptoms start. Even if it means they're at home for longer than 14 days. The most up-to-date public guidance is always online at

If your symptoms are serious, or get worse, NHS 111 has an online coronavirus service that can tell you if you need further medical help and advise you what to do.  Only call 111 direct if you are advised to do so by the online service or you cannot go online.
