Anti-wrinkle injections
Wrinkles can be caused by aging, exposure to ultraviolet rays and repeated facial expressions. Repeated contraction of muscles forms wrinkles! However most people show wrinkles and fine lines with facial movement and expressions such as lifting eyebrows. That's normal. When wrinkles show at rest, that means skin damage. Anti-wrinkle injections (Botulinum toxin) can prevents the nerve from telling the muscle to contract, therefore reduce wrinkles caused by repeated contract

Lip Enhancement - Dermal Filler
Lip enhancement is a less invasive, non-surgical procedure where dermal filler is injected into the lips to add extra volume into the lip area. Dermal filler contains hyaluronic acid, a hydrating, volume-enhancing compound found naturally in the body’s soft tissue.

It offered instant results and myriad benefits including ful

Maxillary Labial Frenectomy
A frenum is the attachment between the gum and some moving soft tissue part of the mouth - typically the tongue (lingual frenum) or the lip (labial frenum). Sometimes this is contributing to a problem with the gums or the alignment of the teeth - particularly when the frenum is attached to the gum right at the level where the teeth emerge. Maxillary labial frenum is capable of creating a diastema and recession, affecting aesthetics. The most common reason for frenectomy is

A better filling makes you feel better.
Symptoms: Tooth felt sensitive. Food got impacted between teeth. Problems: Defective filling with marginal leakage and open contact between teeth. If it had been left un-treated, it would have caused decays on the tooth and the adjacent tooth, gum inflammation and infection because of food impaction. We replaced the old filling. On x-ray, it showed that the new filling achieved tight contact with good margin. No more food impaction - a better filling makes you feel better.

External Root Resorption.
Root resorption is not a common dental condition but it can lead to tooth extraction. There are two main types of resorption that may happen to a tooth: internal and external. The causes of external resorption can be trauma, rapid orthodontic movement and infection etc. The troublesome tooth in this x-ray caused toothache and pus oozing out of gums. On the x-ray, the tooth showed dark area on the root but the margins of the nerve was quite clear. Thus we highly suspected e

This heavy smoker's teeth hadn't been cleaned for years. The mixture of tobacco stains and tartar presented on most teeth. After the thorough clean, all stains on surfaces and tartar were removed. But the stains have settled deep into the cracks of enamel and penetrated into the dentin on the edges of the teeth, w

Zirconia crowns - restore teeth aesthetically and functionally.
Two lower middle front teeth had been worn off because of deep bite. All enamel on front surfaces were gone. Teeth had been fixed a few times with composite resin (whiting fillings) and kept coming off. Teeth became very yellowish due to lack of enamel covering dentine. Zirconia crowns are perfect solution for this case. They are much stronger material than composite resin and last longer. These crowns not only protect teeth from being worn off, but also give an excellent r

Challenge of root canal treatment
Root canal anatomy variations present a constant challenge in successful diagnosis and endodontic treatment , especially the multirooted teeth. The most challenging root for endodontic treatment at the level of location, shaping, avoidance of iatrogenic events, and obturation is the fourth (MB2) canal of the upper first molars. Maxillary first molar is the most commonly treated tooth yet with the highest endodontic failure rate because of undetected canals, especially the mes

Multiple Dental Implants
When a number of teeth are missing, multiple dental implants are the best option to give you the feeling of real teeth and easy maintenance of oral hygiene. In this case, all the premolars and molars are missing, which means there is no back teeth to chew on. A lower partial denture was made but the patient couldn't stand it because of lack of stability and comfort. Eventually three implants resolved all the problems. Three months after implant surgery , the intergrated im

Braces - Give you straight teeth and a confident smile!
This orthodontic case showed how traditional braces fixed teeth with severe crowding. The crooked teeth didn't look good and also created gum problems - gingivitis (reddish around gum lines in "before picture"). Any other options apart from traditional braces? Invisible braces like Invisilign? Unfortunately it may not work well in such a complicated case. In 18 months, crooked teeth were transferred to straight teeth. A confident smile created! #orthodontics

How rapid palatal expansion ( RPE ) works.
This is the result of the orthodontic appliance for rapid palatal expansion ( RPE ). About 8mm maxillary width expansion was achieved in a month with one turn ( 0.25mm ) per day. It's not only correcting the posterior crossbite but also creating space for crowded teeth. The gap between top front teeth showed that the RPE was working very well. But don't worry, the gap will be closed when we put braces on and start straightening the teeth. The link below is how it looked

Internal bleaching after root canal treatment.
It's very common that teeth become discolored after root canal treatment because the dead tissue's pigment penetrates into tooth structure. Aesthetically it doesn't look nice especially for front teeth. Veneers and crowns can cover the discoloration from outside. But they are not only expensive, more importantly, they also damage teeth by removing tooth structure. Internal bleaching whitens the tooth from inside using bleaching agent. Compared to porcelain veneers and cro

RPE - Rapid Palatal Expander
A Rapid Palatal Expander (RPE) is an orthodontic appliance that puts pressure on the upper jaw (maxilla) to separate the mid palatal suture by turning a midline screw. It makes the maxilla wider and creat space. RPEs are used often to correct posterior crossbites. This procedure is better to be done at a younger age before the palatal suture becomes fused. With adults, Surgically Assisted Rapid Palatal Expander (SARPE) is needed, which combines an RPE and surgery performe
