Even a subtle change in your smile helps you to project on the image of self-confidence and high personal esteem.when you feel good about yourself, it shows in your appearance. Today’s advanced techniques and materials can make a real difference.today’s dentistry uses a unique combination of science and artistry can literally redesign your smile. Thanks to advances in modern dental materials and techniques, dentist’s have more ways to create pleasing, natural-looking smiles. Dental researchers are continuing their often decades-long work developing materials, such as ceramics and polymer compounds that look more like natural teeth.as a result, dentists and patients today have several choices when it comes to selecting materials to repair missing, worn, damaged or decayed tooth.

What’s right for me? 

Several factors influence the performance, durability, longevity and cost of dental restorations. These factors include; the patient’s oral and general health, the components used in the filling material; where and how the filling is placed; the chewing load that the. tooth will have to bear, and the length and the length and number of visits needed to prepare and adjust the restored tooth. The ultimate decision about what to use is best determined by the patient in consultation with the dentist. Types of dental restoration. 

There are two types of dental restorations; direct and indirect. 

Direct restorations are fillings placed immediately into a prepared cavity in a single visit.they include dental amalgam, glass ionomers, resin ionomers and some resin composite fillings .the dentist prepares the tooth, places the filling and adjust it during one appointment.Indirect restorations generally require two or more visits. They include inlays, onlays, veneers, crowns and bridges fabricated with gold base metal alloys, ceramics or composites. During the first visit, the dentist prepares the tooth and makes an impression of the area to be restored. The impression is sent to a dental laboratory, which creates the dental restoration. At the next appointment, the dentist cements the restoration into the prepared cavity and adjust it as needed.

Amalgam Fillings 

Used by dentists for more than a century, dental amalgam is the most thoroughly researched and tested restorative material among all those in use.it is durable, easy to use, high resistance to wear and relatively inexpensive in comparison to other materials.for those reasons, it remains a valued treatment option for dentists and their patients. Because amalgam filling can withstand very high chewing loads, they are particularly useful for restoring molars in the back of the mouth where the chewing load is greatest.they are also useful in areas where a cavity preparation is difficult to keep dry during the filling replacement, such as in deep fillings below the gum line.amalgam fillings, like other filling materials, are considered biocompatible they are well tolerated by patients with only rare occurrences of allergic response.Disadvantages of amalgam include possible short-term sensitivity to hot or cold after the filling is placed.the silver-colored filling is not as natural looking as one that is tooth-colored, especially  is near the front of the mouth, and shows when the patient laughs or speaks.and to prepare the tooth, the dentist  may need to remove more tooth structure to accommodate an amalgam filling than for other types of the filling.

Composite Fillings

  • Composite fillings are tooth coloured-fillings.
  • Composite fillings provide good durability and resistance to fracture. In small-to-midsize restorations that need to withstand moderate chewing pressure.
  • Less tooth structure is removed when the dentist prepares the tooth, and this may result in a smaller filling than that of an amalgam.composites can also be ''bonded'' or adhesively held in a cavity, often allowing the dentist to make a more conservative repair to the tooth.
  • The cost is moderate and depends on the size of the filling and the technique used by the dentist to place in the prepared tooth.it generally takes longer to place a composite filling than what is required for an amalgam filling.
  • Composite fillings require a cavity that can be kept clean and dry during filling and they are subject to stain and discolouration over time.


Glass ionomers are translucent, tooth-coloured and can release a small amount of fluoride that may be beneficial for patients who are at high risk for decay. When the dentist prepares the tooth for a glass ionomer, less tooth structure can be removed; this may result in a smaller filling than that of an amalgam. Glass ionomers are primarily used in areas not subject to heavy chewing pressure.because they have a low resistance to fracture, glass ionomers are mostly used in small non-load bearing fillings (those between the teeth) or on the roots of teeth.Indirect restorative dental materials (two or more visits)

Sometimes the best dental treatment for a tooth is to use a restoration that is made in a laboratory from a mould. This custom -made restoration, which requires two or more visits, can be a crown, an inlay or an onlay. a crown covers the entire chewing surface and sides of the tooth. An inlay is smaller and fits within the contours of the tooth.  An onlay is similar to an inlay, but it is larger and covers some or all chewing surfaces of the tooth. The cost of indirect restorations is generally higher due to the number and length of visits required, and the additional cost of having the restoration made in a dental laboratory. Materials used to fabricate these restorations are porcelain (ceramic), porcelain fused to a metal-supporting structure, gold alloys and base metal alloys.
