# Questions and answers > How to check Dr Nazem Al Ioussef's DHA licence, which languages he speaks, where he consults, how appointments are arranged and how this site's health information is written, with short answers to everyday dental questions. Source: https://www.nazemalioussef.com/en/faq/ Updated: 2026-09-28 Plain answers about Dr Nazem Al Ioussef's licence, where he consults and how this website works, followed by an index of the health topics it covers. ## About Dr Nazem and his licence **How can I check a dentist's licence in Dubai?** The Dubai Health Authority (DHA) keeps a public medical registry of licensed professionals, called Sheryan. A professional's entry shows their licensed title, their licence number and status, and the facility where they work. [Dr Nazem Al Ioussef's entry in the DHA registry](https://services.dha.gov.ae/sheryan/wps/portal/home/medical-directory/professional-details?dhaUniqueId=00239613) shows his professional licence number: 00239613-001. **What do “General Dentist” and “Implantology Privilege” mean in his registry entry?** General Dentist is his licensed title: the professional category under which the DHA licenses him. The entry also lists an Implantology Privilege, a clinical privilege for dental implants recorded separately from the title. Both appear here exactly as the registry records them, and the registry itself is the authoritative source. **What is his main clinical focus?** Dental implants, together with bone grafting where the jaw needs it. His clinical interests also include surgical work inside the mouth: removing impacted wisdom teeth, exposing impacted teeth for orthodontic treatment, apicectomy, the removal of cysts, frenum surgery, gingivectomy and the removal of small growths inside the mouth.

Postgraduate training in oral and dental surgery followed in Irkutsk until 1999. The DHA registry also lists graduations from Ajman University in 2016 and the University of Sharjah in 2017.

He has held his Dubai Health Authority licence since August 2011 and has consulted at Liberty Dental Clinic since December 2013. More: [Career](https://www.nazemalioussef.com/en/about/career/) **Which languages does he speak with patients?** He speaks Arabic, English and Russian with patients. **Where does he consult?** At Liberty Dental Clinic, Jumeirah 3, Beach Road, Dubai, United Arab Emirates. The clinic's hours and contact details are given on the [clinic page](https://www.nazemalioussef.com/en/clinic/). **What are the clinic's hours?** What are the clinic's hours? | Monday | 10:00–19:00 | | --- | --- | | Tuesday | 10:00–19:00 | | Wednesday | 10:00–19:00 | | Thursday | 10:00–19:00 | | Friday | Closed | | Saturday | 09:00–21:00 | | Sunday | 10:00–19:00 | Appointments are arranged by Liberty Dental Clinic. **How are appointments arranged?** Appointments are arranged by Liberty Dental Clinic, not through this website. The clinic's phone number is [+971 4 395 5009](tel:+97143955009). **Is this website for emergencies?** No. In a medical emergency in the UAE, call [998](tel:998) for an ambulance, or [999](tel:999) for the police. The guide to [dental emergencies](https://www.nazemalioussef.com/en/patient-guides/dental-emergencies/) explains what to do if a tooth is knocked out, the face swells or a socket keeps bleeding after an extraction. ## Everyday dental questions Short answers, each with a page that explains the subject and lists its sources. **How often should I have a dental check-up?** It depends on the health of your teeth and gums, so the dentist sets the interval for each person. UK guidance from NICE puts it between 3 months and 2 years for adults, and between 3 months and 1 year for children. More: [Cleaning your teeth properly](https://www.nazemalioussef.com/en/patient-guides/cleaning-your-teeth/) **Is it normal for my gums to bleed when I brush?** It is common, but healthy gums do not usually bleed. Bleeding is often an early sign of gum inflammation caused by plaque at the gum line, so it is worth having the gums checked. More: [Gum disease](https://www.nazemalioussef.com/en/patient-guides/gum-disease/) **How much radiation does a dental X-ray involve?** Very little. Dental X-rays use low doses of radiation, and dentists take them only when the image will help with diagnosis or treatment. More: [Dental X-rays and 3D scans](https://www.nazemalioussef.com/en/patient-guides/dental-x-rays/) **What should I do if an adult tooth is knocked out?** Hold it by the crown, not the root. If it is dirty, rinse it quickly in milk or cold water without scrubbing, and put it back in its socket if you can; otherwise keep it in milk and see a dentist straight away. A knocked-out baby tooth should not be put back. More: [Dental emergencies](https://www.nazemalioussef.com/en/patient-guides/dental-emergencies/) **Why do my teeth hurt with cold drinks?** Usually because dentine, the layer beneath the enamel, has become exposed, often where the gum has receded or the enamel has worn. The same pain can also come from decay or a cracked tooth, so pain that lingers after the cold has gone, or affects only one tooth, needs a dentist. More: [Sensitive teeth](https://www.nazemalioussef.com/en/patient-guides/sensitive-teeth/) **What usually causes bad breath?** Most often the mouth itself: bacteria in plaque on and between the teeth, along the gum line and on the tongue. Strong-smelling food, smoking, a dry mouth, fasting and gum disease are other common causes. If it lasts despite careful cleaning, a dentist can look for the cause. More: [Bad breath](https://www.nazemalioussef.com/en/patient-guides/bad-breath/) **When should a child first see a dentist?** Early. The NHS advises a visit once the milk teeth start to come through, and before the age of 1; the American Academy of Pediatric Dentistry says no later than age 1. Early visits also help a child get used to the dentist. More: [Children's teeth](https://www.nazemalioussef.com/en/patient-guides/childrens-teeth/) **I grind my teeth at night. What can help?** Many people do not know they grind until a partner hears it or a dentist sees the wear. Stress, poor sleep, caffeine, alcohol and smoking make it more likely, so easing those can help, and a guard made by a dentist protects the teeth at night. See a dentist if your teeth are worn or your jaw aches. More: [Teeth grinding](https://www.nazemalioussef.com/en/patient-guides/teeth-grinding/) **When should a mouth ulcer be checked?** Most mouth ulcers clear up on their own within a week or two, the NHS says. See a dentist or doctor if one lasts longer than three weeks, keeps coming back, or becomes more painful and red. More: [Mouth ulcers](https://www.nazemalioussef.com/en/patient-guides/mouth-ulcers/) **Do wisdom teeth always need to come out?** No. Wisdom teeth that are healthy and cause no problems are usually left in place, and NICE advises against removing them only to prevent future problems. Removal is considered when they cause disease, such as repeated infection or decay.

Each page lists its sources, says what it rests on, and shows when it was published and last reviewed. They are not a diagnosis or a treatment recommendation for any individual: that needs an examination. **Why does this site not take bookings or list charges?** Because it is the professional profile of a dentist, not the website of a health facility. It sets out his qualifications, his clinical interests and general health information, and it offers no service. Appointments are arranged by Liberty Dental Clinic. **What personal data does this site collect?** It has no forms, no messaging button and no booking tool, and it collects no health information. What it does process, such as the server logs kept by the hosting provider, is set out in the [privacy policy](https://www.nazemalioussef.com/en/privacy/). ## Questions by topic Each page below answers the common questions on its subject, with its sources. ### Clinical interests - [Dental implants](https://www.nazemalioussef.com/en/clinical-interests/dental-implants/) How an implant replaces the root of a missing tooth, and what treatment usually involves. - [Bone grafting and sinus lift](https://www.nazemalioussef.com/en/clinical-interests/bone-grafting-and-sinus-lift/) When there is not enough bone to hold an implant, and how it is built up. - [Impacted wisdom teeth](https://www.nazemalioussef.com/en/clinical-interests/wisdom-teeth/) Why wisdom teeth get stuck in the jaw, and when removal is considered. - [Exposing impacted teeth](https://www.nazemalioussef.com/en/clinical-interests/exposing-impacted-teeth/) When a tooth, often an upper canine, stays buried, and how it is uncovered and guided into place with a brace. - [Apicectomy](https://www.nazemalioussef.com/en/clinical-interests/apicectomy/) A small operation at the tip of a root, when infection remains after root canal treatment. - [Jaw cysts](https://www.nazemalioussef.com/en/clinical-interests/jaw-cysts/) Fluid-filled sacs in the jaw, often found on an X-ray, and how they are removed. - [Frenum surgery](https://www.nazemalioussef.com/en/clinical-interests/frenum-surgery/) Tongue-tie and lip-tie: when a tight frenum matters, and how it is released. - [Gingivectomy](https://www.nazemalioussef.com/en/clinical-interests/gingivectomy/) When gum overgrows and covers part of a tooth: why it happens, and how the excess gum is removed. - [Small lumps in the mouth](https://www.nazemalioussef.com/en/clinical-interests/small-lumps-in-the-mouth/) Common harmless lumps inside the mouth, when to have one checked, and how one is removed. ### Patient guides - [Cleaning your teeth properly](https://www.nazemalioussef.com/en/patient-guides/cleaning-your-teeth/) Brushing, toothpaste and cleaning between the teeth: daily habits that protect teeth and gums. - [Tooth decay](https://www.nazemalioussef.com/en/patient-guides/tooth-decay/) How decay starts, how it progresses, and what stops it. - [Gum disease](https://www.nazemalioussef.com/en/patient-guides/gum-disease/) From bleeding gums to periodontitis, and the daily care that helps prevent it. - [Sensitive teeth](https://www.nazemalioussef.com/en/patient-guides/sensitive-teeth/) Why teeth hurt with cold or sweet things, and what helps. - [Root canal treatment](https://www.nazemalioussef.com/en/patient-guides/root-canal-treatment/) What happens inside a tooth when the pulp becomes inflamed or infected. - [Crowns and bridges](https://www.nazemalioussef.com/en/patient-guides/crowns-and-bridges/) How a weakened tooth is covered with a crown, and how a bridge fills the gap left by a missing tooth. - [Dental emergencies](https://www.nazemalioussef.com/en/patient-guides/dental-emergencies/) What to do if a tooth is knocked out or broken, or the face swells, and when to call 998. - [Dental abscess](https://www.nazemalioussef.com/en/patient-guides/dental-abscess/) What a dental abscess is, why it needs prompt treatment, and when swelling is urgent. - [Dental X-rays and 3D scans](https://www.nazemalioussef.com/en/patient-guides/dental-x-rays/) Why X-rays are taken, and what each kind of image shows. - [Children's teeth](https://www.nazemalioussef.com/en/patient-guides/childrens-teeth/) From a baby's first tooth to a first dental visit: teething, sugar and help with brushing. - [Bad breath](https://www.nazemalioussef.com/en/patient-guides/bad-breath/) Where bad breath usually comes from, what helps, and when it needs a dentist. - [Teeth grinding](https://www.nazemalioussef.com/en/patient-guides/teeth-grinding/) Grinding and clenching, often at night: the signs, the causes and what can help. - [Mouth ulcers](https://www.nazemalioussef.com/en/patient-guides/mouth-ulcers/) Why mouth ulcers appear, how to ease them, and when one needs checking.
