In fact, most food that contains sugar can be metabolized by bacteria in plaque on the surface of teeth to produce acid which will lead to cavition on the enamel, causing tooth decay.

Therefore, by having snacks frequently, there will be continuous production of acid in the plaque on the surface of the teeth with insufficient time for the saliva to neutralize the acid. This acidic cavity environment will favour the development of tooth decay. To prevent tooth decay is not only to prevent eating sweets, but also to reduce the frequency of snacking.

其實，所有食物只要含有糖分，便會把牙齒表面的牙菌膜分解，產生酸素，侵害牙齒表層的琺瑯質，而形成蛀牙。所以如果飲食的次數過於頻密，牙齒表面的牙菌膜持續產生酸素，卻沒有足夠的時間讓唾液中和過多的酸素，便容易形成蛀牙。因此，預防蛀牙的方法並非只是不吃甜食，還要減少飲食的次數。

Teeth Whitening as Easy as 123

Your teeth become discolored because of…
Extrinsic Staining - (1) smoking (2) Pigments in beverage and foods
Intrinsic Staining - (1) Genetics (2) Dental developmental disorders (3)Antibiotics (4) Age

Routine dental cleaning can only help to remove extrinsic staining. But for intrinsic stains, peroxide based chemical agent is required. This process is commonly known as teeth bleaching. The two common tooth bleaching methods are home and in-office bleaching.

Home Bleaching
Products may include:
1. Whitening toothpastes
2. Whitening strips and gels
3. Tray-based tooth whiteners

In-Office Bleaching
Products deliver higher concentrations of peroxide than home bleaching.

亮白牙齒 Easy as 123

您的牙齒變黃，可能是因為…
外在原因 - (1) 吸煙 (2) 食物及飲品色素
內在原因 - (1) 遺傳 (2)先天牙齒缺憾 (3) 長期服用抗生素 (4) 年齡

定期洗牙有助清除外來性的污漬，但要對付內在因素的染色，便要用到一些具有過氧成份的美白劑，從而減淡色素。這個過程稱為牙齒漂白，而牙齒漂白分為兩種: 家居漂白及診所漂牙。

家居美白
產品包括:
1. 美白牙膏
2. 美白牙貼
3. 美白牙托

診所漂牙
使用高濃度的牙齒漂白劑

隱藏智慧齒實在存風險

不少病人以為自己沒有長智慧齒，卻有可能是他們的智慧齒完全藏在牙肉或牙骨內，難以察覺。別以為這類牙齒看不見又沒有痛楚，便不成問題，反而存在風險。例如引致前面大牙的牙根吸收或形成囊腫等病理。

Risks of ‘Hidden’ Wisdom Teeth

Some people might think they do not have any wisdom teeth; in fact, they might be completely buried in the gums or dental bones. Hidden wisdom teeth might cause the neighbouring bone to absorb or formation of cyst.

防蛀食物

香口膠
咀嚼香口膠能刺激唾液分泌，增加唾液中和作用，但一定要無糖香口膠﹗餐後食一粒無糖香口膠，能有效預防蛀牙。

Food for Healthy Teeth

Chewing gum
Chewing gum can stimulate the secretion of saliva which can increase the acid neutralization in the oral cavity, but the chewing gum will preferably be sugar-free! Eating a sugarless chewing gum after meal can effectively prevent tooth decay.

長期流牙血或有口臭?

長期牙肉流血及有口氣，很可能已患上牙周病。牙周病的成因是牙菌膜長期積聚在牙齦(牙肉)邊緣，而牙菌膜分泌的毒素令牙周組織發炎，因此患有牙周病是會引發持續性牙肉流血和產生口氣。早晚使用含氟化物的牙膏清潔牙齒及牙肉邊緣有助減輕病情。要徹底清潔牙齒就必須同時使用牙線及牙縫刷。

Gum bleeding or having bad breath for a long time?

Persistant gum bleeding and bad breath may be caused by periodontal disease, which is related to the accumulation of bacteria in the form of dental plaque at the margin of the gingivae. Toxins released from bacteria can cause irritation and damage the surrounding periodontal tissues. Regular tooth brushing with toothpaste in the morning and especially in the evening to clean the surfaces of the teeth and gum can ease the symptom. A more thorough cleaning can be achieved by the use of dental floss and interdental brushes.

何謂根管治療？

根管治療又稱牙髓治療或杜牙根，是指清除受感染或壞死的牙髓組織，然後把牙髓填封。這樣有助清除牙髓內的細菌、阻止牙髓再受感染及蔓延至牙周組織和牙槽骨，使牙齒得以保存。若牙齒經過牙髓治療後變得脆弱，便要鑲配牙套以加強牙冠保護。

What is an Endodontic Treatment?

Endodontic treatment involves the removal of infected or injured pulpal tissue. The pulp chamber and root canal(s) will be cleaned and sealed to stop/prevent further bacterial infection. If the tooth structure is too weak after treatment, extra protection will be needed by putting on a crown.

運動時如何保護牙齒

運動牙膠可以在有身體接觸的運動保護你口腔免受傷害，有些研究指出配戴運動牙膠比沒有配戴,能均勻地吸收和卸去撞擊時所產生的衝擊力。因此，原本受到撞擊的一、兩隻牙齒不需要承受所有的衝擊力。

How to protect your teeth during sport?

Sport guard is used to protect you in close contact sports from oral injuries. Some studies have shown that sport guards are able to absorb the force of an impact and distribute this force more evenly compared to not wearing a sport guard. Therefore, the impact will not concentrate only on one or two teeth.
