Hyaluronic acid fillers

With years, skin looses its moisture and becomes thinner. Lines and wrinkles start to settle. Hyaluronic acid injections can help smoothing them without surgery.

What is hyaluronic acid?

Hyaluronic acid is naturally present in the body. Like a sponge, it absorbs water and maintain the skin deep layers hydrated. It’s possible to inject this molecule as a gel to give volume and plump the skin or smooth wrinkles. The hyaluronic acid will mix with the one contained in the body and will progressively resorb. It is advised to have regular injections done, between  3 and 12 months depending  on patients and area treated. Reversibility is an advantage compared to the permanent effect of a cosmetic surgery.

What can we treat?

The most common treatments concern the naso-labial and marionette lines around the mouth. It’s also possible to reshape the lips or give them more definition, or contour the face and add volume on the cheekbones but also sharpen a jawline or enhance a chin.

The treatment in itself

Most of product contain local anesthetic but some don’t. A numbing cream can be applied before to improve the comfort during the injection. The procedure is quite quick, beetween 15 and 30 minutes depending on which areas are treated. A massage of the area will be performed to make sure the product is well placed.

The results

They are visible instantly but the the effects are optimum about 2-3 weeks after the injection when the body integrates the molecule and pumps water. The treated area may swell for a few days, bruise or present redness, but you can apply make up while everything is getting back into order. Depending on people, their metabolism and their personal habits (cigarette, sun exposure, physical activity), injections have to be repeated every 3 to 12 months.


There are very few as the molecule is naturally present in the body, the risk of allergy is extremely low. Injections should be avoided when pregnant or breastfeeding.

Protecting permanent teeth with Fissure sealants

french-dentist-children-londonSee full article in L’Echo Magazine: Londres version française, April-May 2017, page 45 by Francine Joyce.

Fissure sealants are prevention treatments for permanent teeth, treating mostly molars and premolars for children from age 6. Brushing is often difficult due to the lack of access. These sealants protect the natural grooves on the chewing surface of the teeth (80% of tooth decays start in these grooves/fissures for children), brushing is made easier as the retention of food debris is reduced and they often contain fluoride to reinforce the protection.

The procedure is simple, quick and painless: only a few minutes per tooth including the clean of the fissures, preparation of the surface with an acidic gel and the application of the fluid resin which will be light-cured to set instantly.

It’s very important to have them checked regularly, they can last for years but sometimes need replacement.



Why a sensitive toothpaste may help

Teeth sensitivity can be related to numerous factors (tooth decay, inflammation of dental pulp, gum recession, loss of enamel…). The first thing to do is to book a consultation with your dentist to identify the cause and make a treatment plan.

When the layer of enamel is affected or when the gums recede, the use of sensitive toothpaste may help to reduce the sensitivity. The little canals that transmit the nervous impulse can be exposed. Sensitive toothpastes usually have 2 main mechanisms of action

1) A mechanical and mineralizing action by obturation of these canals (strontium salt, fluoride combined with other ions)

2) A neutralizing action by deactivation of the nervous impulse (potassium salt)

Dermal fillers for smoker lines

FILORGA dermal filler used for the smoker lines (also called barcode lines, they are the vertical wrinkles above the upper lip) , treatment performed at Make Me Feel by Dr TL.

The vertical lines are reduced and the volume is more harmonious, which also give the upper lip a nice shape, though the lip itself has not been directly treated. The “after” picture was taken just after the procedure and the skin will smooth out a bit further after a few days.

Dental Prevention Visit at La Petite Ecole Française, North Kensington, London

prevention-bucco-dentaire-enfants-londresDr Thu-Linh ALLAIN NGUYEN, French dentist in London, visited La Petite Ecole Française this month to promote oral health with children aged 5 to 10 years old. They learned how to keep healthy teeth with fun activities and videos. The 3 key-points are:

1) Toothbrushing, at least twice a day, morning and evening under parents supervision

2) A balanced diet, without snacking and with a reasonable amount of sugar to reduce the cavity risk (be careful with the sugary drinks like fruit juice and fizzy drinks)

3) A consultation with the dentist once to twice a year to get them used to the dental examination, for early detection of problems and treatments, and to monitor the growth and eruption of the baby teeth and permanent teeth

6 years-old is a key age for teeth with the eruption of the first permanent teeth, the upper and lower incisors (“front teeth”) after loss of baby teeth but also the first permanent molars, often forgotten because no baby tooth is lost before their appearance at the very back of the mouth. They may get decayed because of difficulty of access when brushing but they can be protected by Fissure sealants (quick and easy painless treatments to facilitate the brushing and add a fluoride protection).

Thu-Linh also works with le Lycée Français Charles de Gaulle de Londres, in particular with l’Ecole André Malraux in Ealing.



Bruxism is excessive teeth grinding or jaw clenching with symptoms such as hypersensitive teeth, aching jaw muscles, pain around the temporomandibular joint, headaches, tooth wear, damage to teeth and dental restorations. There are two types of bruxism: sleep bruxism and awake bruxism. People affected by bruxism are not necessarily aware of their condition because  the contraction of the mastication muscles is unconscious.



Some visible signs on the teeth are: abfraction (tooth tissue loss along the gingival margin caused by bio mechanical loading forces), gum recession and attrition (tooth wear with loss of tooth anatomy, flat and shorter teeth).

As the teeth become flatter and shorter, sensitivity may occur: the dental pulp containing the dental nerve is not as well protected by the layers of dentin and enamel tissues.

To prevent damage to the teeth, mouthguards or appliances (splints) are often used. Treatment performed by Dr TL:


Bruxism is a complex pathology and should be part of a multidisciplinary care. Injections of Botulinum Toxin (Botox) can partially paralyze the mastication muscles and lessen their ability to forcelly grind and clench while enabling normal activities such as talking and eating. These injections will also allow the dentist to restore the teeth with fillings, crowns, bridges, veneers, putting them less at risk of fracturing. Meet Dr Marie-Hélène Marion to know more about Bruxism et Botulinum Toxin.

Working with osteopaths is also beneficial. Florence Pasteur, Osteopath takes into account the dental factors when treating body posture.

Emax onlay

Large dental fillings may break under important or repetitive mastication forces. This can also lead to the fracture of the tooth itself, sometimes beyond repair. Onlays are a good way to restore a tooth and they are superior in terms of resistance than direct fillings. They are also more conservative than crowns. Treatment performed by Dr TL.


Dental impressions are taken during the first appointment and the onlay is glued on the second appointment. Onlays can be made in gold or porcelain. In this case, an Emax porcelain has been placed.

Maryland bridge

A Maryland bridge can be a great option to replace a missing tooth with minimal removal of dental tissue. Treatment performed by Dr TL.


When it’s not possible to consider an implant to replace a missing tooth (for technical or financial reasons), a Maryland bridge is a good compromise to restore the aesthetics of the smile without too much preparation of the abutment teeth. Depending on cases, one or two wings will be glued at the back of the adjacent teeth.
