What is Sealant?
A sealant is a synthetic material used to seal joints or openings in structures. It is an essential building material used in a variety of applications, including roofing, window and door installation, fence and deck building, interior drywall construction, and waterproofing. Sealants are also used for a variety of industrial purposes, such as to fill gaps in machinery and equipment, or to create watertight seals.
Sealants are made from a variety of materials, such as silicone, acrylic, and polyurethane. They are typically applied as liquid or paste-like substances, and then allowed to dry and harden. The most common way to apply sealants is with a caulking gun.
Types of Sealants
There are several types of sealants available on the market. They differ in composition, cost, and application. Some of the most popular types of sealants are:
- Acrylic Sealants: Acrylic sealants are inexpensive and easy to use. They are typically used for roofing and interior painting jobs. Acrylic sealants are durable, waterproof, and provide a strong bond.
- Silicone Sealants: Silicone sealants are more expensive than acrylic sealants, but provide greater flexibility and a stronger bond. They are waterproof and long-lasting, making them ideal for waterproofing and sealing. Silicone sealants are also extremely temperature-resistant.
- Polyurethane Sealants: Polyurethane sealants are more expensive than acrylic or silicone sealants, but offer superior flexibility and strength. They are also resistant to water, UV light, and chemicals. Polyurethane sealants are best suited for outdoor applications such as roofing and waterproofing.
- Latex Sealants: Latex sealants are inexpensive and are commonly used in interior projects such as drywall. They offer less flexibility and durability than silicone or polyurethane sealants, but are ideal for use in areas where high flexibility is not necessary.
- Polysulfide Sealants: Polysulfide sealants are more expensive than other types of sealants, but provide superior adhesion and flexibility. These sealants are particularly well-suited for use in high-temperature, harsh environments.
Symptoms of a Needed Sealant
The most obvious sign that a sealant may be needed is a crack, hole, or gap in a surface. Other symptoms of a needed sealant may include visible damage in the form of fading or cracking of existing sealant and leakage or water damage around the affected area.
Causes of a Needed Sealant
The main cause of the need for sealant is weathering. A variety of environmental factors such as wind, rain, and extreme temperatures can cause sealant to deteriorate, or weaken over time. A lack of maintenance can also cause sealants to become brittle and crack.
Diagnosis of a Sealant Need
If the need for a sealant is suspected, a qualified professional should inspect the area. They will determine whether the area needs to be sealed and the type of sealant needed. A range of tests, such as water or penetration tests, may need to be carried out to ensure the proper diagnosis is made.
Treatment of Sealant Needs
Once a sealant is needed, it should be applied as instructed by a qualified professional. After the sealant is applied, it should be left to cure according to the manufacturer’s instructions. If the sealant is not applied correctly, it could lead to further problems or a decrease in the effectiveness of the sealant.
Benefits of Sealants
There are several benefits to using sealants in a variety of applications. Here are just a few:
- Prevents water penetration: Sealants can prevent water from entering a structure, which can cause significant damage. Sealants provide a barrier between the elements and the structure, helping to prevent moisture, mold, and mildew from forming.
- Prevents air infiltration: Sealants can help prevent air from entering the structure, which can lead to energy inefficiency and increased utility bills. Air sealants can help block out drafts and reduce energy costs.
- Reduces sound transmission: Sealants can help reduce sound transmission, which can be important for creating quiet, comfortable spaces.
- Aesthetically pleasing: Sealants can also be aesthetically pleasing. They can help blend in with the surrounding environment or add a touch of color to a structure.
- Durable: Sealants are designed to stand up to harsh weather conditions such as extreme temperatures, wind, rain, and snow. Properly applied sealants can last for years.
Practical Tips for Using Sealants
Here are some practical tips for using sealants:
- Always follow the manufacturer’s instructions when applying a sealant.
- Use the right sealant for the job. Different sealants are best suited for different jobs, so it’s important to choose the right one.
- Fill any cracks or gaps before applying the sealant for the best possible results.
- Allow the sealant adequate time to cure. Different sealants require different curing times, so make sure to check the manufacturer’s instructions for proper curing.
- Use a protective sealant to keep the sealant from deteriorating over time.
- If possible, use a sealant that has been tested and certified by a reputable organization.
Sealants are an essential building material used for a variety of applications. Sealants can help prevent water and air infiltration, reduce sound transmission, and provide a pleasing aesthetic. Different types of sealants are best suited for different applications, so it’s important to choose the right one and use it properly. With proper care and maintenance, sealants can provide years of protection and beauty for a structure.
Definition and Overview
Sealants are thin, plastic coating materials that are placed on the teeth’s surface to protect them from tooth decay. They are most commonly used on the molars and premolars to prevent dental caries from settling in the teeth’s natural grooves and fissures, which are dangerous hiding places for cavities. Plaque also accumulates more easily on these back teeth because they are not fully protected by saliva and fluoride due to their location. Once the sealants are applied, however, the material bonds with the teeth’s grooves and creates a full shield over each tooth.
How Sealants work
The back teeth, namely the molars and premolars, are highly susceptible to cavities, dental caries, and tooth decay because they are hard to reach with a toothbrush or dental floss. Due to the extra challenge in keeping these teeth clean, they are more vulnerable to plaque. Sealants work by keeping food particles from getting into the nooks, grooves, and fissures of the back teeth.
Due to their protective function, sealants are now commonly regarded as a basic component in dental hygiene. In addition, they are also proven to be beneficial in the management of lesions caused by dental caries.
Dental caries refer to the process wherein the minerals naturally found on the surface of a tooth gradually disappear due to the bacteria and acids that collect in the mouth while chewing food. This loss of minerals is counteracted by saliva and fluoride, which help new minerals to form. However, since molars and premolars are often beyond the reach of saliva and fluoride, they receive very limited protection compared to the other teeth. Thus, there is more loss of minerals than there is gain and this ultimately causes dental caries.
With dental caries now considered as the most common oral disease that attacks teeth even at a young age, the protection provided by sealants is crucial.
Who should get Sealants
Since sealants are designed to protect the teeth, it is best to get them at a young age. The most advisable age for getting sealants is between 6 and 14 years old. These are the years when children are most prone to cavities and dental caries. At six years old, most children get their permanent molars and premolars, which make it a good time to begin the protective process.
However, adults and younger children will also benefit from sealants. Adults with healthy teeth should get them to further protect their teeth from damage and decay, which become more common as a person ages.
Younger children, such as toddlers with baby teeth, may also get sealants, especially when the teeth have deep grooves. Keeping a child’s baby teeth healthy will also help maintain proper spacing for when the permanent teeth come in. In addition, getting sealants will ensure that children don’t lose their baby teeth earlier than they should.
What to expect during your dental appointment
For sealants application, you should see your dentist or your dental hygienist.
This protective procedure is performed at the dentist’s clinic and can be completed in a single visit. The process is simple, painless, and only takes a few minutes for each tooth. This does mean, however, that if several of your teeth need a sealant, the procedure will take longer.
Prior to the application of the sealants, each tooth is first cleaned thoroughly and dried. An acid solution that roughens up the tooth surface may also be required to ensure that the protective coating bonds quickly with the surface of the tooth after application. This, however, depends on the type of sealant used. If an acid solution is used, the teeth have to be rinsed and dried for the second time.
Once the teeth are prepped, the sealants will be applied. Once placed on the tooth, the material quickly hardens. The dentist may also speed up the hardening process by applying a special curing light.
How long can Sealants protect teeth
Sealants offer long-term protection of up to 10 years, which make them a highly cost-effective preventive measure for proper dental health maintenance. Nevertheless, dentists still need to periodically check them for chips and cracks, which can be easily repaired. This means that even with sealants on, you still need to schedule your regular dentist’s appointment at least once every six months. If damaged sealants are detected, your dentist will replace them with new ones.
Are Sealants covered by dental insurance
As a basic preventive procedure, sealants are covered by most dental insurance policies. To be certain, however, check with your insurance provider first before going to the dentist for sealants.
