Dentifrice is a preparation for cleansing and polishing the teeth, more commonly known as toothpaste. There is a wide varieties of toothpaste on the market some contain agents for whitening (stain removal), fluoride (inhibit formation of dental caries), or triclosan (inhibit formation of gingivitis and plaque). The two that were selected in this comparison were chosen because they are the ones I use on a regular basis. The reality is that there are so many different oral care products out that it becomes a overwhelming experience when shopping for the best products that fit a specific need. I except a lot from my toothpaste, I need a good taste, accuracy to complete the job, reasonable prices, a certain texture and of course how long will it protect me from bacteria.While choosing a toothpaste I had to consider some factors, I have very sensitive skin (eczema) and teeth so I have to be cautious to what I put on my skin, especially around my mouth. When it came to choosing a toothpaste research lead me towards Sensodyne. I normally use Sensodyne Deep Clean because it works inside the tooth to help calm the nerves for 24 hours and leaves a lasting sensation of freshness with foam boost technology and fresh mint flavor. Sensodyne is specially formulated to relieve sensitivity. Sensitive toothpaste is designed to block the dentine tubules and minimize sensitivity when brushing. Also I never had a cavity before and this toothpaste says it has cavity prevention, so I figured it would prevent me from getting them in the future as well. I also tend to use Crest 3D White Radiant Mint Whitening Toothpaste when I feel my teeth are getting a tinted yellow from my dietary habits. I also like using it because it uses a patented enamel-safe teeth whitening ingredient that polishes away stains to gently whiten teeth. In fact, it removes up to 80% of surface stains and protects against future stains, strengthens teeth and contains fluoride that protects against cavities, all while having a radiant Mint flavor. With its unique formula it protect and whiten teeth with a cool blast of mint as part of the complete dental health regimen. 3D White fluoride toothpaste also strengthens the tooth’s enamel and helps protect against cavities.The active ingredients in Sensodyne Deep Clean are Potassium nitrate and its purpose is antihypersensitivity and Sodium fluoride purpose is anticavity. The inactive ingredients are water, hydrated silica, sorbitol, glycerin, pentasodium triphosphate, PEG-8, sodium lauryl sulfate, flavor, xanthan gum, sodium hydroxide, cocamidopropyl betaine, sodium saccharin, and blue 1. The inactive ingredients in Crest 3D White Radiant Mint are very similar to that of Sensodyne Deep Clean but the Crest has disodium pyrophosphate, sodium lauryl sulfate, cellulose gum, carbomer, mica, along with the water, sorbitol, hydrated silica, flavor, sodium hydroxide, sodium saccharin, xanthan gum, polyethylene, titanium dioxide, blue 1 lake. Crest 3D White has only one active ingredient which is the same as Sensodyne; Sodium fluoride and its purpose is anticavity.I plan to incorporate the information learned regarding different toothpastes in my future purchases. The different ingredients in toothpaste is very important because it’s what sets them apart from one another. Each ingredient does something different to treat an oral condition. Though price may also affect customers decision to buy many customers also choose toothpaste bases on how white their teeth would be, will it protect against cavities, will it work for my sensitivity, or will it reverse my gingivitis, manufacturers need to be aware of such things. This is where the vast varieties of toothpaste come from, there are so many needs for different oral conditions that just one toothpaste won’t do. For instance, Crest 3D White and Sensodyne both protect against cavities and use fluoride, but one whitens teeth and the other is a deep cleaning product that work inside the tooth to clean. Both very useful depending on the patients conditions yet so different when it comes to purposes of treatment.
