Frequently asked questions
Dentist FAQ in Casablanca: your questions on teeth and gums
Brushing, pain, gums, whitening, children, pregnancy… here are the Smiles & Beyond centre’s answers to everyday dental questions. They are for guidance only: only an examination allows a diagnosis.
Daily brushing and hygiene
How many times a day should I brush my teeth?
Twice a day, morning and evening, for about two minutes, with fluoride toothpaste. Evening brushing matters most because saliva decreases overnight.
How should I brush my teeth properly?
Tilt the brush 45° towards the gum and make small gentle movements on every surface of the teeth, without scrubbing hard. Brush your tongue too. Brushing too hard can damage the gums.
Manual or electric toothbrush: which one?
Both work if the technique is good. An electric brush often helps you brush more regularly and for longer. Choose soft or medium bristles, never hard.
Is dental floss really necessary?
Yes: a brush cannot reach the spaces between teeth, where many cavities and gum problems begin. Use floss or interdental brushes once a day, preferably in the evening.
Do I need mouthwash?
It is not compulsory. It complements brushing but does not replace it. Antiseptic mouthwashes should not be used for long without the dentist’s advice, as they can stain teeth.
How often should I change my toothbrush?
About every three months, or as soon as the bristles spread. Change it after a sore throat or a mouth infection too.
Gums, tartar and bad breath
Why do my gums bleed when I brush?
Most often because plaque and tartar irritate the gum (gingivitis). Do not stop brushing: carry on gently and have a scaling. If bleeding persists, a gum assessment is needed.
How can I get rid of bad breath?
Brush your tongue, clean between your teeth and have regular scaling. Bad breath most often comes from the mouth (plaque, gums, cavities); if it persists, talk to your dentist or doctor.
What is tartar and can I remove it myself?
Tartar is hardened dental plaque. It cannot be brushed off and should not be scraped at home, which risks damaging enamel and gum. Only a dentist can remove it.
Are loose teeth a serious sign?
Tooth mobility in an adult should always be examined: it can signal gum disease or an injury. The earlier it is treated, the better the chance of keeping the tooth.
Why are my gums receding?
Brushing too hard, gum disease, smoking, grinding or misaligned teeth can cause it. Gums do not always grow back by themselves: see a dentist before the root is exposed.
Dental pain and emergencies
What should I do with a toothache?
Rinse gently with lukewarm water, avoid very hot or cold food and contact the centre quickly. A painkiller may relieve it temporarily on your doctor’s or pharmacist’s advice, but it does not treat the cause.
Why are my teeth sensitive to cold and heat?
Worn enamel, receding gums, a cavity or a crack can be the cause. Toothpaste for sensitive teeth can help, but the cause must be found.
What if a tooth is broken or knocked out?
Keep the fragment or tooth without rubbing or disinfecting it. A whole knocked-out tooth can sometimes be replanted if you act very fast: keep it in milk or saline and call the centre immediately.
What is a dental abscess?
An infection at the tip of the root or in the gum, with throbbing pain, swelling and sometimes fever. It needs a quick consultation, because the infection does not go away by itself.
My cheek is swollen: what should I do?
Facial swelling with pain or fever may signal a dental infection. See a dentist the same day. If you have trouble breathing or swallowing, or a high fever, go to the emergency room.
Can a tooth that had a root canal still hurt?
Slight discomfort may last a few days after treatment. Pain that lasts or returns may signal an infection or a crack: tell your dentist.
Cavities and everyday treatments
How do I know if I have a cavity?
A white, brown or black spot, sensitivity to sweets or cold, food getting stuck: all possible signs. But many cavities are painless at first: only a check-up with X-rays can detect them.
Does a filling last a lifetime?
No. Its lifespan depends on its size, the material, hygiene and chewing. Regular check-ups let the dentist monitor it and redo it before a new cavity forms.
Why does a tooth need a root canal?
When the nerve is infected or irreversibly damaged, a root canal lets you keep the tooth instead of extracting it. The tooth is then rebuilt, often with a crown.
Should wisdom teeth be removed?
Not systematically. They are removed when infected, decayed, badly positioned or damaging neighbouring teeth. A panoramic X-ray or scan helps decide. See wisdom teeth extraction.
How often should I see the dentist?
Usually once or twice a year for a check-up and scaling. The schedule is adapted to your risk of cavities and gum disease.
Whitening and smile aesthetics
Is teeth whitening dangerous?
Done by a dentist after an examination and with suitable products, whitening is considered safe for healthy teeth. Temporary sensitivity is possible. Avoid unsupervised products.
Why are my teeth turning yellow?
With age, enamel thins and shows the yellower dentine underneath. Coffee, tea, tobacco, red wine and some medicines also stain teeth. Scaling removes surface stains; whitening lightens the shade.
Do activated charcoal or baking soda whiten teeth?
They can remove surface stains but are abrasive: used often, they wear enamel and make teeth more sensitive. Supervised whitening by a dentist is better.
How can crooked teeth be corrected in adulthood?
It is possible at any age if the gums are healthy, often with clear aligners (Invisalign) or fixed braces. An assessment helps choose the method.
Implants and missing teeth
How can a missing tooth be replaced?
With an implant, a bridge or a removable denture. The choice depends on bone, neighbouring teeth, your health and expectations. Do not leave a gap unexamined: neighbouring teeth can drift.
How long does a dental implant last?
Well placed and well maintained, it can last many years. Lifespan depends on hygiene, follow-up, smoking and general health.
Can an implant be placed at any age?
There is no strict age limit, but you need enough bone, healthy gums and a health condition compatible with surgery. An assessment with a 3D scan checks this.
Children’s teeth
At what age should my child first see a dentist?
As soon as the first teeth appear or around age 1, for a first discovery visit. Then a check-up about every six months.
Do baby teeth need treatment?
Yes. A cavity in a baby tooth causes pain and infection and can affect the permanent tooth. See children’s dentist.
How can I help a child who is afraid of the dentist?
Talk about it in simple words without mentioning pain, and choose a practitioner who takes their time. The first visit can be without treatment, just to discover the clinic.
Do dummies or thumb-sucking harm teeth?
Used beyond age 3 or 4, they can deform the palate and move teeth. A dental opinion helps stop the habit gently.
Pregnancy, health and appointments
Can I go to the dentist while pregnant?
Yes, check-ups and necessary treatment are possible, preferably in the second trimester. Always tell the dentist you are pregnant. Gums bleed more easily, so good follow-up helps.
Are dental X-rays dangerous?
Modern digital devices use very low doses and images are only taken when useful. See dental X-rays. Mention a possible pregnancy.
Is dental treatment painful?
Treatment is done under local anaesthesia when needed: you should not feel pain. Tell us if you are afraid or something bothers you.
