Why Do My Teeth Look More Yellow After Whitening Strips

Mar 15, 2022

Teeth Whitening Strips Overview


Almost anyone would jump at the idea of altering their smile; this might include a plethora of treatments that range from orthodontics to replacing missing teeth and even brightening stained teeth. One of the most sought-after dental treatments is teeth whitening.


Having a dazzling smile will boost your confidence. It will also command attention whenever you get into a room. This is why the demand for teeth whitening products has exponentially increased over the past few years, and the number keeps on rising.


This demand has led to companies scrambling to make different products that promise to give you a whiter smile. Nevertheless, you will need to be careful since not all products deliver what they advertise. Plus, others may cause severe side effects, especially if they are not used according to the instructions.


At times people opt for home teeth whitening since they are cheaper and can be done in the comfort of the house. Some people may opt for teeth whitening strips since they can be found at the local store. So, let’s see what happens when you go for teeth whitening strips. So, contact our dentist near you at Complete Dental Works in New York to schedule an appointment.


Teeth Whitening Strips 101


Teeth whitening strips contain ingredients that remove the tooth stains. They contain peroxide, a type of bleach that removes stains from teeth. Most manufacturers use hydrogen peroxide, but others prefer to use carbamide peroxide.


The teeth whitening strips are made of plastic and are coated with peroxide gel. So, when you apply the strips to your teeth, the peroxide that covers the strips will work on the teeth to remove the stains. Peroxide breaks down the stains within the tooth and reduces the concentration of the stains making your teeth look whiter.


You will likely wear the strips for about 30 minutes once or twice each day. You will have to do this for about 14 days to see some change.


There are instances where you might use teeth whitening strips, and instead of your teeth becoming white, they turn yellow. This can be very confusing and also disheartening.


What Does the Yellow Sign Indicate?


Teeth whitening strips use peroxide to remove stains. So what happens is that the peroxide temporarily increases your enamel’s porosity. This allows the peroxide to reach the discolored molecules in your teeth.


However, it can be a disadvantage for some people since it creates an avenue for your teeth to be stained. When you eat or drink teeth-staining beverages and foods, such as coffee, red wine, and even smoking, you can stain your teeth.


On the other hand, teeth whitening strips can cause the enamel to erode and will expose the underlying tooth structure. Also, if you have poor oral health or an underlying medical condition that affects the teeth, the teeth whitening procedure may make the teeth yellow.


This is because the dentin has a yellowish hue under the enamel. So, when the enamel thins, your teeth become translucent and may look yellow.


Is There Any Loss On Dental Health While Using Whitening Strips?


Some people opt for teeth whitening strips because they are very convenient. You go to your local store, buy the strips, and incorporate them into your daily teeth cleaning routine. However, the ingredients used in some of them can be harsh on your teeth and gums.


Some problems that may arise when you use teeth whitening strips are:


  • Tooth sensitivity – This is because teeth whitening strips can make your teeth a bit more sensitive because the peroxide can pass through the enamel and reaches the dentin. The dentin has tubules that communicate with the nerves, so the peroxide irritates the nerves.
  • Gum irritation – the peroxide in the whitening strips can irritate your gums. This usually happens when you misuse the strips or wear them too long. But it might last for a few days.
  • Tooth damage – In some cases, the peroxide may destroy some parts of your teeth, causing erosion and demineralization.


The whitening strips should be used according to the instructions. If you use them for too long, it might harm or affect your oral health.


That’s why it is best to receive professional teeth whitening in West New York, which guarantees safety, improvement in your dental health, and instant results.

Can Dental Impressions Pull Teeth?

10 Nov, 2022
Dentists require images of your teeth, gums, and surrounding structures to create diagnostic models of your mouth for various purposes. For example, dentists take dental impressions of the teeth, gums, and oral structure when providing different treatments to restore teeth. In addition, the images are essential for creating whitening trays, retainers, mouthguards, et cetera. Traditional impressions are pretty familiar in dentistry, although advances now make digital teeth impressions popular similarly. Dental Impressions Explained If you are unaware of dental impressions, these are mere imprints of the structures inside your mouth. A special putty helps make conventional dental impressions in use for several years. However, dentistry advances have given dentists access to digital teeth images that they take using a handheld wand and computer software to capture mouth pictures. How Do Dental Impressions Help? Dental impressions help create models and casts of your mouth to enable dentists to view the fitting of your dental arches. They also help your dentist to see the size and relationship of your teeth and gums. In addition, dental impressions allow for various dental restorations and oral appliances. For example, if you need restorations of damaged or missing teeth, the dentist requires impressions of your mouth to have dental crowns, bridges, dentures, veneers, clear aligners, retainers, teeth whitening trays, sports mouthguards, night guards, and sleep apnea oral appliances. The restorations mentioned above either help to fix damaged or missing teeth, protect your teeth from sustaining damage, or help improve their aesthetic appearance. Therefore dental impressions help in various ways to provide images of your teeth and mouth to the dentist to custom-create models of your mouth for dental laboratories to fabricate your restorations. Kinds of Dental Impressions Three types of dental impressions are familiar in dentistry. They are preliminary, final, and bite registration. Preliminary impressions help fabricate dental prostheses such as crowns and dentures during the diagnostic process or the initial step in the procedure. The Teaneck dentist generally takes impressions during your initial visit for a consultation. Preliminary impressions provide dentistry with a visual aid to plan your treatment. Final impressions are taken for the dental laboratory to fabricate restorations or appliances. For example, dentists might have crowns, bridges, dentures, retainers, etc., manufactured from the putty dental laboratory using final impressions. Bite registration impressions display how your upper and lower teeth fit together. What Happens When Taking Dental Impressions? The dentist might use dental putty or the latest technology when making dental impressions of your mouth. The procedures for taking the images vary but provide similar results. Traditional dental impressions require the dentist to dispense a putty-like dental impression material in a plastic or metal tray. After that, the dentist places the trays over your teeth, asking you to bite on them. A minute or two later, the rental impression material sets and hardens. Eventually, the dentist removes the trays from your mouth beside the impression material. The impressions are for the dental laboratory, where a technician will pour stone into the impression to make a cast of your mouth. Presently digital impressions in Teaneck are gaining popularity because dental offices are increasingly investing in them to capture thousands of images of your teeth and gums. Digital prints do not require your dentist to prepare trays with putty to take digital impressions. Instead, the dentist in Teaneck passes a wand over your teeth to view your mouth on a computer screen and capture the images. The computer stitches the pictures to create a digital 3D image of your dental arches. The dentist forwards the digital graphics electronically to the dental lab, where the technician starts working on your requirements. Can Dental Impressions Pull Teeth out? In most cases, dental impressions will likely not pull teeth out. Digital dental images make it impossible for the wand to remove teeth from your mouth. Unfortunately, if you have loose teeth from trauma or periodontal disease, you might experience pulling of the teeth with traditional impressions. You can discuss the possibility of your teeth getting pulled by traditional impressions before your consultation to ensure the professional uses the digital variety. What Is the Cost of Dental Impressions? The cost of dental impressions varies according to the purpose they are needed for and the dentist’s expertise besides your geographical location. However, if you are visiting dentists for restorations like dental implants or veneers, the professionals provide a free consultation during your meeting and will likely not charge for the impressions unless you want them merely to look at the insides of your mouth. In addition, dental impressions are standard tools of the trade of dentists who use them frequently when providing minor or significant dental treatments to patients. Therefore the cost of dental impressions should not remain a concern in your mind unless you contact the dentist for frivolous reasons unrelated to any dental procedure or want to pull the dentist’s leg for reasons unknown. If you need restorations like indirect fillings or teeth whitening from Complete Dental Works — Teaneck expects the dentist to capture digital impressions of your mouth to create the fillers and teeth whitening trays. You will have to pay for the whitening trays, while the images for the restorations will likely be on the house. Therefore contacting this practice for your dental treatments is suggested for access to the latest technology, helping provide excellent services.

Why Do My Teeth Hurt After Whitening Strips?

15 Oct, 2022
What are Whitening Strips, and How Do They Work? Whitening strips are thin plastic strips that you put on your teeth. They contain peroxide, which bleaches your teeth.  Your dentist will apply them to the surfaces of your teeth using suction or adhesive and then let them sit for 30-60 minutes (usually) before rinsing them off with water. Whitening strips are usually used once a day for several days to achieve the best results. It is not recommended to use the whitening strips overnight because they can cause gum irritation and sensitivity. Why Do My Teeth Hurt? Teeth sensitivity The use of whitening strips can cause sensitivity. However, it isn’t permanent and can be reduced with time and continued care. If you are sensitive to the bleaching agents found in your teeth-whitening strip, try using them less often or switch brands altogether. Using a low-strength whitening strip may also help reduce sensitivity if your mouth is sensitive to stronger chemicals used in these products (such as hydrogen peroxide). If you experience extreme pain or irritation when brushing or flossing, we recommend you visit a dental office near you for treatment. The dentist will assess the gums and recommend the appropriate treatment. Irritation to the gums Gum irritation can occur because it may contain harmful chemicals, which can irritate the tissue of the gums. The irritation causes swelling of the tissue around the teeth, which causes discomfort and pain in some people. Stop using the whitening strips immediately if you experience any sensitivity or soreness after using them. How to Ease Teeth Sensitivity While Using Whitening Strips? Teeth sensitivity happens because the tooth enamel becomes thinner and less protective after the whitening process. To reduce teeth sensitivity while using whitening strips, you must use a desensitizing toothpaste or mouthwash. You will also need to avoid acidic foods with high sugar content. How Often Should You Whiten Your Teeth? The frequency of teeth whitening is dependent on the condition of one’s teeth. If you have sensitive teeth, you should whiten them every six months. If someone has stained teeth, they should whiten them quarterly or every three months. The more frequently you whiten the teeth, the more likely the whitening results will last longer. How Do I Naturally Whiten My teeth? There are many natural ways to whiten teeth, like baking soda and peroxide. This method will not only give you whiter teeth, but it will also remove plaque and improve your gum health. An easy way to whiten your teeth is by using mouthwash or toothpaste with a whitening agent or activated charcoal. This can help remove stains on the surface of your teeth and make them appear whiter. Baking is a natural, non-toxic, and inexpensive remedy for teeth whitening, and it is easy to use. When brushing, use the baking soda for a minute, and rinse your mouth thoroughly with water. However, baking soda can erode the enamel and weaken the teeth. However, the best option is getting professional teeth whitening services in West New York for better results. Furthermore, the dentist protects the gums from irritation by applying the protective gel before the tooth whitening procedure. How to Prevent Teeth Discoloration? Teeth discoloration can happen because of age or consuming too much coffee, tea, red wine, and other beverages that contain tannins. Smoking or chewing tobacco can cause the teeth to discolor. There are many ways to prevent teeth discoloration , and some of them are as follows: Avoid drinking coffee, tea, and red wine. Avoid smoking cigarettes or using tobacco products. Brush your teeth with baking soda mixed with water every day to remove stains from your teeth.
