Brushing is the best method for dental care. It not only whitens teeth but also extends their lifespan and prevents tooth loss. Those who neglect brushing naturally have less healthy teeth. However, individuals with cavities or missing teeth should not despair—the field of cosmetic dentistry is so advanced that it can help everyone. First, let's introduce the common filling materials used in daily practice. There are various types of filling materials, and the choice depends on the specific situation.
1. By Material Properties:
(1) Amalgam: Composed of mercury and alloy powders;
(2) Resin: Includes synthetic composite resins and natural gutta-percha;
(3) Metal Salt Cements: Such as zinc phosphate cements.
2. By retention time in the cavity:
(1) Short-term materials: Used for temporary cavity sealing during treatment. Clove oil zinc oxide cement can be used for up to 2 weeks, while zinc phosphate cement can be used for up to 6 months;
(2) Long-term materials, i.e., permanent filling materials that replace defective tooth structure for extended retention, such as silver amalgam and composite resin.
Common Cases and Treatment Solutions
(1) Dental Caries
a. Technical Principles
Dental caries refers to a chronic, progressive disease affecting tooth hard tissues caused by multiple factors, primarily bacteria. Generally classified into shallow, moderate, and deep types, caries treatment requires different approaches based on severity, such as artificial fillings, root canal therapy, or cosmetic crowns.
b. Technical Procedures
① Oral examination to determine cavity type and number.
② Thorough removal and disinfection of diseased tissue.
③ Cavity preparation: Removal of decayed material followed by cavity shaping.
④ For mild decay, inlays may be used for restoration;
For moderate to deep cavities with pulp damage, root canal therapy is typically performed—first treating the pulp, then filling the defect;
Both scenarios can also be addressed with cosmetic crowns, which restore function while enhancing aesthetics.⑤ Finishing touches: Surface polishing and staining may be performed.
c. Recovery time
Postoperative swelling typically subsides naturally within 3-5 days, with full recovery occurring around one week. Normal work and daily activities are generally unaffected.
d. Postoperative care
① Avoid brushing teeth on the day of composite filling to prevent dislodging the material.
② While the tooth's shape is restored, its chewing function is partially compromised. Avoid hard foods and refrain from chewing on the treated side initially.
③ The filling material requires time to set. Avoid eating for 2 hours after the procedure. After this period, consume light, mild liquids or semi-liquids such as milk, bread, porridge, or soups.
④ While the cavity is controlled after filling, poor oral hygiene can still lead to decay.Therefore, oral hygiene is crucial. Maintain daily care by brushing teeth morning and night, rinsing after meals, and scheduling regular dental check-ups.
⑤ Mild discomfort or pain is normal and will subside over time. However, if pain worsens instead of improving, consult your dentist promptly for adjustments or repairs.
(II) Traumatic Tooth Restoration
a. Technical Principles
Traumatic tooth restoration primarily addresses wedge-shaped defects and trauma-induced damage. Clinically, both are treated similarly: artificial materials are used for repair based on the extent of the defect, or cosmetic crowns may be fitted.
b. Technical Methods
① Conduct an oral examination to determine the number of teeth requiring restoration.② Thoroughly remove diseased tissue and disinfect the area.
③ Prepare the cavity by removing the damaged tooth structure and shaping the cavity.
④ Perform targeted restoration based on the extent of the defect using porcelain-fused-to-metal or composite resin materials; cosmetic crowns may be placed if necessary.
⑤ Fine finishing: Polish and shade-match the tooth surface.
c. Recovery Period
Postoperative swelling typically subsides naturally within 3-5 days, with full recovery occurring around one week.
d. Aftercare Instructions
1. Avoid hard, sticky, or acidic foods for 2-3 days.
2. Maintain regular oral hygiene practices.
3. Avoid excessive chewing pressure on the restored tooth for 2-3 days.
4. Follow the dentist's specific aftercare instructions.
5. Schedule a follow-up visit as advised by the dentist.⑤ Finishing touches: Polish and shade the tooth surface. c. Recovery Time Postoperative swelling typically subsides naturally within 3-5 days, with full recovery occurring around one week. Normal work and daily activities are generally unaffected. d. Postoperative Care ① Avoid brushing teeth on the day of composite filling to prevent dislodging the material.
② While the tooth's shape is restored, its chewing function is partially compromised. Avoid hard foods and refrain from chewing on the treated side initially.
③ The filling material requires time to set. Avoid eating for 2 hours after the procedure. After 2 hours, consume light, mild liquids or semi-liquids such as milk, bread, porridge, or soups.
④ Although tooth function is restored after filling, neglecting oral hygiene may lead to cavities.Therefore, oral hygiene is crucial. Maintain daily care by brushing morning and night, rinsing after meals, and scheduling regular dental check-ups.
⑤ Mild discomfort or pain is normal and will subside over time. However, if pain worsens instead of improving, consult your dentist promptly for adjustments or repairs.
Replacing missing teeth is straightforward, yet proper care demands patience from those who value their appearance. Dental maintenance isn't a quick fix. For instance, some individuals brush only once daily—while diligent, this effort is insufficient. The most effective approach to truly nurture your teeth is to brush more frequently,Avoid spicy foods, rinse frequently—these simple steps are well within your reach.
