A very popular preventive treatment, dental sealants are designed to protect the teeth from cavities and decay. They are applied to the chewing surfaces of molars and premolars because they are more prone to decay.
Sealants act as a barrier and prevent food particles and bacteria from settling in the deep grooves and fissures. Many people, however, wonder if dental sealants are long-lasting, and the answer depends on several factors.
Keep reading below to learn how long the dental sealants last and what factors are associated with them.
What are Dental Sealants?
Dental sealants are a thin, protective coating of plastic resin material painted onto the surfaces of molars and premolars. The primary purpose of sealants is to protect teeth from cavities, plaque buildup, and decay by filling the deep grooves and fissures. This helps prevent food particles and bacteria from getting trapped on the chewing surfaces.
It is a simple, non-invasive procedure that usually involves the following steps:
- Cleaning the teeth
- Applying an acidic gel to help the sealant bond
- Rinsing the tooth and drying it
- Painting the sealant over the enamel to cover deep grooves and fissures
- Curing the sealant with a special light to harden it
How Long Do Dental Sealants Last?
Dental sealants can last anywhere between 5 to 10 years. Here are some factors that affect the longevity of sealants:
Type of Sealant Material
The material used for dental sealants plays a significant role in their lifespan. The two main types of dental sealants are:
- Resin-based Sealants
- These are made from plastic
- These are durable but may wear down over time due to chewing
- They generally last between 5 to 10 years
- Glass Ionomer Sealants( Less Common)
- These have the ability to release fluoride, which helps remineralize the tooth
- They tend to wear away more quickly than resin-based sealants
- They typically last 3 to 5 years
Oral Hygiene Habits
Practicing good oral hygiene helps extend the lifespan of dental sealants. Brushing and flossing on a regular basis makes the sealants less likely to wear down. However, neglecting proper oral care may result in plaque buildup and decay, leading to the sealants breaking down faster.
Dietary Habits
Eating habits play a vital role in the longevity of dental sealants. It is best to avoid consuming hard or sticky foods, which may cause the sealants to chip or wear down. These include hard candies, ice, and chewing on non-food items, which may cause damage to the sealants.
Bruxism
Clenching and grinding the teeth, even during sleep, can cause dental sealants to wear down quickly. Since bruxism causes unnecessary stress, dental sealants tend to crack. Therefore, if you have the habit of grinding your teeth while sleeping, wearing a night guard can protect your teeth as well as your sealants.
Final Verdict!
Dental sealants can protect your teeth from decay, plaque buildup, and cavities. Their effectiveness and longevity, however, depend upon various factors, including oral hygiene, dietary habits, and whether you grind your teeth. With proper care, dental sealants can last up to 5-10 years.
