Your dentist can help you find the right whitening product or procedure to help you get a brighter smile. Whiteners may not correct all types of discoloration, especially if you have brown or gray hued teeth. If you have had bonding or tooth-colored fillings placed in your front teeth, the whitener will not affect the color of these materials, and they will stand out in your newly whitened smile. You may want to investigate other options, like porcelain veneers or dental bonding. Some other ways to get a whiter smile are:  In-office bleaching is a dental procedure in which dentist applies either a protective gel to your gums or a rubber shield to protect the oral soft tissues, which is followed by a bleaching agent. This procedure can be done in one visit to the dentist’s office. At-home bleaching with products containing hydrogen peroxide is useful for some people. There may be potential side effects, such as increased sensitivity or gum irritation, so speak with your dentist before using any whitening products. Whitening toothpastes help remove surface stains and reduce discoloration over the long term with a proper oral care routine. A dental x-ray can help your dentist detect any signs of damage or disease in your teeth that may not be visible during a regular check-up, which may be the cause of teeth discoloration. If you frequently experience toothaches or bleeding gums, an x-ray can help your dentist understand the cause better.  If you are a new patient, your dentist may recommend getting an x-ray to determine the current status of your oral health. A new set of x-rays may be needed to help your dentist detect any cavities, analyze your gum health or evaluate the growth and development of your teeth.

Problem: Article: You can use bar soap or dishwashing soap. Make sure the ring is evenly coated before sliding it on the mandrel. A ring mandrel is a graduated metal cone, which is used to size rings. You can easily obtain them from general online retailers. Your strikes should be gentle yet firm. Strike at a downward angle; you’re essentially trying to move the ring further down the mandrel. Make sure to turn the ring as you strike, to evenly stretch it.  If you have access to it, use a vice to secure the mandrel. This will make this step much easier. If you only have access to a carpenter’s hammer, you should cover the ring with a soft cloth to prevent damage to the band. If it’s still too tight, you can repeat the process, placing the ring on the mandrel and hammering until it fits. Keep in mind this method can only stretch a ring about half a size. If the ring is struck, you can strike upwards with the mallet to dislodge it.
Summary: Lubricate the ring with soap and slide it onto a ring mandrel. Gently tap the ring with a wooden mallet or jeweller’s hammer. Remove the ring from the mandrel and try it on.

Q: Website optimization involves using the right keywords and headlines to show up at the beginning of online searches. This is an essential element when it comes to improving traffic to your website. Incorporating images and accurately labelling them will help you in this process. This process is often referred to as SEO, which stands for Search Engine Optimization. If you have optimized a website to show up under search terms for your business, include the same keywords alongside an accurate image descriptor to title your photo. This will ensure that users are linked to your page when searching for the images that correspond to the content on your website.  You can also use your URL keywords to keep it simple. If your URL title is “buy-our-stuff.html,” and you’re selling hats, label an image “buy-our-stuff-hat-1.jpeg.” If you’re using keywords to make your images show up more often on search engines but the descriptive titles of your images aren’t accurate, you’re harming your user’s experience. Alt tags are hidden text that are revealed in browsers used by the visually impaired. This text is read by search engines however, which makes it an excellent place to include keywords or search terms that you may not need to list publicly. Keep these tags accurate though—you don’t want to sacrifice visibility for accuracy. If there is important information that you want to include for your user but don’t want to include in your image tag, put it in a caption. Captions could include commentary or clarifying information about an image, and will bolster your image’s profile without bogging down the title.  Captions are the small little quotes or lines that go underneath an image—usually in a smaller font than the rest of your content. An example of a caption for a photograph of a president giving a speech could be, “The president speaking at a benefits concert before the opening act."
A:
Understand how optimizing your website informs searches. Copy headline and URL keywords to make accurate image labels. Include keywords in the image information and alt text. Use captions to provide additional information on your site.
