Ice cube vs tooth, one of them is going to give way. But which one?
Dr Gordon Tam • December 23, 2019
It is a satisfying moment to bite on an ice cube from our drinks. Do you know what damage it may potentially cause?

What is a tooth crack?
Tooth crack is a crack found on a tooth structure. It may start from a craze line and the crack gets deeper and bigger. Depending on how deep is the tooth crack, if the crack is deep enough to hit the nerve chamber, you may possibly feel pain when biting on it or sensitive to temperature.
Why did my tooth crack?
Tooth crack can be due to several reasons. One of the most common reasons is you bite on something hard and caused the crack.
- Biting on something hard - ice cube, hard candy, bones, nuts
- Teeth grinding - accumulative pressure exerted to the teeth subconsciously when you are sleeping. The force can be great. In this case, tooth crack may no longer be just 1 tooth but possibly on multiple teeth.
- Trauma or injury to the mouth
- Wear and tear
Can a cracked tooth heal by itself?
Unfortunately, a cracked tooth cannot heal by itself. Our teeth are one of the rare body parts that will not heal or regenerate by itself. So as we always advise you, seek dental treatments early.
Complications of a cracked tooth
- Crack goes deeper from the tooth surface to the nerve, this causes sharp pain when you bite and tooth sensitivity to hot/cold.
- Food trap and bacteria get into the crack, it is impossible for you to clean through the crack
- Gum starts to swell and bleed when the food traps for some time. You will feel gum swollen and soreness
- Tooth decay begins to develop and aggravate the tooth crack issue
- Treatment becomes more complicated as the crack deepens
- Eventually leads to loss of tooth if no or delayed treatment
Symptoms of a cracked tooth
- Sharp pain when biting
- Sensitive to temperature
- Throbbing pain
These symptoms do not go away until the problem is addressed. In some cases, most of the time, the cracked tooth needs to have a crown to replace it. However, if the crack hits the nerve, a root canal treatment is required before the crown.
On some severe cases of a crack tooth that is beyond salvage, we will propose to remove it and replace it with a dental implant.
Treatment
- Crown
- If the crack progresses and causes injury to the nerve, it will require root canal treatment, then followed by a crown
- Severe crack tooth, unable to save, need to be extracted and replaced by an implant or a dental bridge

Your smile is one of the first things people notice about you — but more importantly, it reflects your overall health and wellbeing. Whether you want to restore your dental health after years of neglect or enhance your smile's appearance, you’re not alone. Many people feel self-conscious about their teeth, but the good news is that modern dentistry offers numerous ways to help you regain your confidence and maintain a healthy, beautiful smile for years to come.

Most people are aware that they should visit the dentist regularly, but many underestimate the importance of these routine visits. A dental checkup is not just about keeping your smile looking good—it’s essential to maintaining your overall health and well-being. Here’s why you shouldn’t skip your regular dental appointments.

Most people expect dental problems to improve after treatment. A filling, a crown, a root canal — these are meant to solve the issue and relieve discomfort. But sometimes, a dental problem lingers despite repeated visits to the dentist. If you are stuck with persistent pain, sensitivity, or discomfort that never seems to resolve, you are not alone, and you do have options.

Facing a recommendation for complex dental treatment—such as root canal therapy, dental implants, orthodontics, or full-mouth rehabilitation—can be overwhelming. These procedures often involve significant costs, time, and long-term impact on your oral health. It is natural to feel uncertain or even skeptical. In such situations, seeking a second opinion is a wise and responsible decision.

Everyone notices a great smile. It radiates confidence, leaves a lasting impression, and can even change how you feel about yourself. The best part? You don’t have to be a celebrity to achieve one. With proper care and a few lifestyle changes, anyone can enhance their smile. Here’s a guide to some effective ways to improve your smile!

Almost all of us needed a dental filling at some point of time in our lives. A dental filling is a restoration work done to our tooth that might have chipped off or decay. There are several choices of materials used to replace the partial missing tooth structure. Dental fillings will deteriorate over time, due to wear and tear, bad habits, or even simply they were not properly done in the first place.

What is a dental treatment plan? A dental treatment plan is a detailed plan that the dentist documents his findings after an oral examination. It reflects the current condition of each tooth that may require treatment. This treatment plan gives you a clear idea of the ideal and recommended treatment options and treatment fees. You will also know how long each treatment will take so that you can better plan your dental treatments into your schedule. In Smile Design Dental Practice, we conduct a thorough tooth-by-tooth examination, taking photographs with our intraoral camera and microscope. After the examination and dental charting, our dentists will share with you your current oral condition and customize a treatment plan. We listen to your needs and concerns, understand your considerations on time and budget. The treatment plan is customized to suit your considerations.

Many people pay more attention to adult teeth as the adult teeth will accompany us throughout the majority of our lifespan. While this is true, it is also very important to pay special attention to our baby teeth. Toddlers who are teething at this stage, are also starting to take in semi-solids and converting from liquid to solid food. Our baby teeth play a vital role here to chew well so that the food get digested properly, and absorb nutrients for growth.
