When it comes to restoring decayed or weakened teeth, dental crowns have become indispensable. However, like all the other dental restorations, they have limited lifespans. In this article, we explore the average lifespan of dental crowns.
Factors That Determine the Lifespan of Dental Crowns
- Material Used: Gold crowns for instance are known to be resistant to corrosion, and are less likely to wear down than other materials. All-ceramic crowns are more prone to cracks with time.
- Technique of Placement: The placement technique is another critical factor to consider when it come to comes to crown longevity. If placed incorrectly, issues like tooth decay, gum irritation, or even crown failure could occur. The dentist should make sure the crown fits over the tooth with no spaces to prevent bacteria build-up.
- Oral Hygiene Practices: Brushing and flossing are necessary to prevent food particles and bacteria build-up. Repeated occurrences of decay affect the gums and finally threaten crown stability.
- Regular Dental Check-Ups: Regular dental check-ups at a reputable dental clinic, such as Diamond Smile, are necessary to ensure that the conditions of the dental crowns are well monitored, and problems can be easily recognised at their starting stage.
Most problems identified in their early stages, can be treated with minor adjustments or repairs, before they spike in severity.
Average Lifespan of Various Kinds of Dental Crowns
- Porcelain-Fused-to-Metal Crowns: Average porcelain-fused-to-metal crowns can last between 10 to 15 years. Some last longer with proper care. The metal base provides a strong base, and the porcelain overlay gives it that look of a natural tooth. One downside is that the metal base tends to wear with time, particularly if the gums recede.
- All-Ceramic Crowns: These crowns can last 10 to 15 years also. All-ceramic crowns do not have metal content; as a result, this is a great choice for someone who is allergic or sensitive to metals.
- Gold Crowns: Gold is highly resistant to corrosion and requires very minimal removal of the tooth structures during its fixation. Gold crowns are the best type of restorative method that is well suited for molars, since the strength of the teeth in those areas are more important than the aesthetics.
Signs That Call for Crown Replacement
Discolouration could result from staining by certain edibles as well as liquids. A crown should be replaced immediately if it is not the same colour as the other teeth to maintain a uniformed look. Another is pain or sensitivity around a crowned tooth. This often occurs due to dental caries, a loose crown, or gums that have receded enough to expose the root of the tooth.
Tips for Prolonging the Lifespan of Dental Crowns
- Good Oral Hygiene: Brushing at least twice a day, using fluoride toothpaste and regular flossing prevents plaque accumulation and decay around the crown.
- Avoiding Harmful Habits: The patient should avoid chewing hard objects like ice, pens, or fingernails, as they could crack or chip the crown. If the patient is suspected to have nocturnal bruxism, then a nightguard will help in the protection of the crowns, while sleeping.
Final Thoughts
To keep crowns as long as possible, it is imperative that you consult a dentist once you notice any signs of damage, to immediately correct the problem or to be advised on crown replacement if needed. Practicing good oral hygiene, and avoiding harmful habits like chewing ice and other hard substances also help prolong the lifespan of dental crowns.
