Hong Kong Filling Materials Guide: What the Procedure Involves and What to Ask Your Dentist

How dentists treat tooth decay in Hong Kong: when a filling is enough, when root canal treatment is needed, and how to care for your fillings afterwards.

Tooth decay is a pain that both men, women and children can experience. If treatment is not performed as soon as possible, it may cause more complications. In general, the most common treatments for tooth decay can be divided into two types: filling and root canal treatment.

What is the difference between filling and root canal treatment? Routine cases are handled by the general dental team at Home Dental Centre, with appointments arranged according to the dentists on duty. If clinical assessment indicates another area of care, the centre will arrange a further assessment with the appropriate dentist, and dentists from different areas can jointly develop a combined treatment plan.

It is generally accepted that tooth decay requires filling. In fact, the effective treatment method is to depend on the severity of tooth decay. If the situation is not too serious, the decay part can be drilled out first, then fill it with filling material. However, if the range of tooth decay is large and the infection is relatively serious, it is necessary to completely remove the infection in the pulp cavity by the root canal treatment. When the tooth decay has already reached a serious stage, extraction is needed.

Why filling is needed?

Tooth decay brings pain to patients, because teeth themselves do not have self-healing function, if the tooth is not filled timely, the pulp cavity will be exposed whilst dental pulp disease will be induced. The role of filling is to rebuild the health of the affected teeth whilst preventing any further developments of tooth decay and avoid winding up in tooth extraction. There are various filling materials on the market, but which one suits you best? Don’t worry, the above table analyzes the characteristics, composition, advantages and disadvantages of four common filling materials for you, you can take your time to consider. To choose the most suitable filling material, you can consider the hardness, wear resistance, aesthetics, cost and other aspects. Besides, the most important thing is certainly, to follow the advice given by a professional dentist regarding the condition of tooth decay. Where a filling is no longer enough, crown materials involve a similar trade-off between appearance and strength.

How to take care of the teeth after filling

Don't assume that once you finish filling, you can do it once and for all. If you don't have proper follow-up care, your teeth can be damaged. Precautions as well as care methods after filling are as follows:

* Avoid chewing hard objects within three days after filling, so as not to deform or even damage the materials.

* If there is mild pain after filling, you can observe yourself first. If the pain has not been alleviated, but further aggravated, you should timely go to the hospital for re-examination, in order to find out the cause to eliminate the pain.

* Although the tooth decay condition is under control after filling, tooth decay can still occur if oral cleaning continues to be ignored. Therefore, in daily life, you should pay attention to brushing your teeth in the morning and evening, rinsing your mouth after meals, following the doctor's instructions and going for regular follow-up and oral examination.

* To protect the teeth after filling, try to avoid biting hard objects with crown, drink less strong tea, smoke less and avoid using metal.

FAQ

Frequently Asked Questions

  • How much does a tooth filling cost?

    Filling costs start from HK$850 per tooth, depending on the material chosen and the extent of decay. Composite resin, amalgam, glass ionomer and gold inlay each have different price points. Quality lies in fully removing decayed tissue and placing a void-free filling — a poor seal leaks and re-decays, later requiring more extensive treatment. After a clinical assessment we explain the fee components clearly, and treatment starts only with your consent. We'll provide a personalised quote after examining your tooth — WhatsApp us to arrange a consultation.

  • What's the difference between a filling and root canal treatment?

    A filling is used when decay hasn't reached the pulp — the dentist removes the decayed part and fills the cavity. Root canal treatment is needed when infection has spread into the pulp chamber, requiring complete removal of infected tissue. Your dentist will recommend the appropriate treatment based on how deep the decay has progressed.

  • How long does a filling procedure take?

    Most straightforward fillings can be completed in a single visit, typically within 30 to 60 minutes. The exact duration depends on the size and location of the cavity, and the filling material chosen. More complex cases may require additional time or a follow-up appointment.

  • Will I feel pain after getting a filling?

    Mild sensitivity or discomfort for a few days after filling is normal and usually subsides on its own. Avoid chewing hard objects for the first three days. If pain worsens or persists beyond a few days, contact us for a re-examination to identify and address the cause.

  • Which filling material is best for me?

    The best material depends on the tooth's location, the size of the cavity, your budget and aesthetic preferences. Composite resin offers natural appearance, amalgam provides durability, glass ionomer releases fluoride, and gold inlay is highly durable. Your dentist will recommend the most suitable option after assessing your specific case.

  • Can I get another cavity after having a filling?

    Yes, new decay can still develop around or near a filled tooth if oral hygiene isn't maintained. Brush twice daily, rinse after meals, and attend regular check-ups. Proper care ensures your filling lasts longer and prevents further tooth decay.

  • What should I avoid eating after a filling?

    Avoid chewing hard foods, ice or sticky sweets for at least three days after your filling to prevent deformation or damage to the material. Also reduce strong tea, coffee and smoking, which can stain composite fillings. Follow your dentist's specific aftercare instructions for best results.
