In the past decade or so, it seems Indian folks have become quite conscious when it comes to dental health, it is observed that more and more people, who are unsatisfied with the way their teeth look, and with the availability of quality dentists now, India is becoming a hot-spot for dental care.
In today's article I am going to talk about two things, teeth whitening Delhi and ceramic crowns Delhi.
Teeth Whitening
What Is It?
Tooth whitening lightens teeth and helps to remove stains and discoloration. Whitening is among the most popular cosmetic dental procedures because it can greatly improve how your teeth look. Most dentists perform tooth whitening.
Whitening is not a one-time procedure. It will need to be repeated from time to time if you want to maintain the brighter color.
What It's Used For
The outer layer of a tooth is called the enamel. The color of natural ...
... teeth is created by the reflection and scattering of light off the enamel, combined with the color of the dentin under it. Your genes affect the thickness and smoothness of the enamel. Thinner enamel allows more of the color of the dentin to show through. Having smoother or rougher enamel also affects the reflection of light and therefore the color.
Every day, a thin coating (pellicle) forms on the enamel and picks up stains. Tooth enamel also contains pores that can hold stains.
The most common reasons for teeth to get yellow or stained are:
Using tobacco
Drinking dark-colored liquids such as coffee, cola, tea and red wine
Not taking good care of your teeth
Aging also makes teeth less bright as the enamel gets thinner and the dentin becomes darker.
It is also possible to have stains inside the tooth. These are called intrinsic stains. For example, intrinsic stains can be caused by exposure to too much fluoride as a child while teeth are developing. Other causes include tetracycline antibiotics. They can stain a child's teeth if taken by a mother during the second half of pregnancy or by a child who is 8 years old or younger. Teeth are still developing during these years. Trauma may also darken a tooth.
Tooth whitening is most effective on surface (extrinsic) stains.
How It's Done
There are two main types of whitening procedures. Non-vital whitening is done on a tooth that has had root-canal treatment and no longer has a live nerve. Vital whitening is performed on teeth that have live nerves.
Non-Vital Whitening
Vital whitening may not improve the appearance of a tooth that has had root-canal treatment because the stain is coming from the inside of the tooth. If this is the case, your dentist will use a different procedure that whitens the tooth from the inside. He or she will place a whitening agent inside the tooth and put a temporary filling over it. The tooth will be left this way for several days. You may need this done only once, or it can be repeated until the tooth reaches the desired shade.
Vital Whitening
The most common type of vital tooth whitening uses a gel-like whitening solution that is applied directly to the tooth surface. This product contains some form of hydrogen peroxide.
Tooth whitening can be done in the dentist's office or at home. In-office (chairside) whitening allows your dentist to use a more powerful whitening gel. A specialized light or laser activates the gel and allows bleaching to happen faster.
In-office whitening usually takes 30 to 90 minutes. You will need one to three appointments. The number will depend upon the method used, how severe your stains are and how white you want your teeth to be. Different types of stains respond differently to the treatment.

Ceramic Crowns.
Why Is a Dental Crown Needed?
A dental crown may be needed in the following situations:
To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
To restore an already broken tooth or a tooth that has been severely worn down
To cover and support a tooth with a large filling when there isn't a lot of tooth left
To hold a dental bridge in place
To cover misshapened or severely discolored teeth
To cover a dental implant
To make a cosmetic modification
For children, a crown may be used on primary (baby) teeth in order to:
Save a tooth that has been so damaged by decay that it can't support a filling.
Protect the teeth of a child at high risk for tooth decay, especially when a child has difficulty keeping up with daily oral hygiene.
Decrease the frequency of sedation and general anesthesia for children unable because of age, behavior, or medical history to fully cooperate with the requirements of proper dental care.
In such cases, a pediatric dentist is likely to recommend a stainless steel crown.
What Types of Crowns Are Available?
Permanent crowns can be made from stainless steel, all metal (such as gold or another alloy), porcelain-fused-to-metal, all resin, or all ceramic.
Stainless steel crowns are prefabricated crowns that are used on permanent teeth primarily as a temporary measure. The crown protects the tooth or filling while a permanent crown is made from another material. For children, a stainless steel crown is commonly used to fit over a primary tooth that's been prepared to fit it. The crown covers the entire tooth and protects it from further decay. When the primary tooth comes out to make room for the permanent tooth, the crown comes out naturally with it. In general, stainless steel crowns are used for children's teeth because they don't require multiple dental visits to put in place and so are more cost- effective than custom-made crowns and prophylactic dental care needed to protect a tooth without a crown.
Metals used in crowns include gold alloy, other alloys (for example, palladium), or a base-metal alloy (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown's porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.
All-resin dental crowns are less expensive than other crown types. However, they wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns.
All-ceramic or all-porcelain dental crowns provide better natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.
Temporary versus permanent. Temporary crowns can be made in your dentist's office, whereas permanent crowns are made in a dental laboratory. Temporary crowns are made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by a lab.
