HONG KONG, Jan. 4, 2023 /PRNewswire/ -- While most Westerners prefer trimmed meat and fish fillets, a vast majority of Asian diners enjoy eating their food off bones, picking flesh from carcasses, and gnawing on tendons, cartilage, and bones for gooey, chewy textures1.

Hong Kong, a food paradise in Asia, is home to many popular Cantonese dishes like steamed pork ribs and phoenix talons served in rattan steamers, juicy roasted geese drumsticks and mouth-watering sweet and sour pork ribs. These are commonly consumed dishes that the locals love.

However, one should exercise caution when consuming such dishes, as it increases the risk of masticatory accidents such as unexpected biting on a hard object, and in this case, stray bone fragments that are often hidden. These create tiny crack-lines on teeth, some on the surface while some are deeper into the dentine and may progress and extend into the dental pulp causing pain and sensitivity.

Higher risk of cracked tooth in Hong Kong especially during Chinese New Year

Especially during Chinese New Year, Hongkongers may consume more traditional snacks like sesame seed balls, melon seeds, candies, and nuts for their symbolic and auspicious meanings. These snacks apart from being sugary and sticky are also hard in nature and often requires a chewing force exerted so much that it can cause micro cracks to develop in the enamel structure.

According to a professor from HKU Faculty of Dentistry, cases of patients complaining about chewing pain, unexplainable sensitivity to hot/cold foods and all symptoms of "cracked tooth" often peaks during festive seasons2.

In 2015, 78% of cracked tooth cases were received in Q1 and most of these cases were aged 35 - 55 years old2.

The American Association of Endodontists defines a cracked tooth as an incomplete tooth fracture in which the enamel and dentin are broken apart or separated by external forces.

A cracked tooth is often difficult to diagnose and locate because symptoms appear inconsistently, and cracks may be too small to be observed. A cracked tooth can begin with craze lines on the enamel or a fractured cusp, or it can be a crack that does not separate the tooth fragment, or a crack that completely splits the tooth, and can even be a direct vertical root fracture3.

Weakened enamel can crack easily under pressure

In most cases of cracks, initial demineralisation of teeth caused by ageing, in which teeth are exposed to eroding agents for long periods of time, may already be present, causing instability and weakening of the enamel and thus causing the teeth to crack easily under pressure.

Teeth can also be weakened and easily chip off from decay and caries that eats up the enamel. Bacteria in our oral biome produce acids to break down sugar, causing demineralisation of enamel; therefore, bacterial removal is critical to prevent demineralisation and teeth from cracking.

Preventing cracked tooth starts from using the right toothpaste

Aside from keeping an eye on your diet and the effects it can have on your teeth, another method of prevention is to keep your teeth healthy and strong.


Dr. Frederic Meyer, an oral health scientist, emphasizes the importance of using a hydroxyapatite-containing biomimetic enamel toothpaste. He explains that the tooth enamel is made up of 97% hydroxyapatite, and that hydroxyapatite in toothpastes is a non-toxic active ingredient that can help repair microscopic enamel defects, remineralise demineralised teeth, and prevent decay and caries to keep teeth healthy and strong, preventing and reducing the risk of cracks. The efficacy of hydroxyapatite-containing oral care products has been tested in several different scientific studies4
