Here are the methods which can efficiently clean your teeth as part of your dental care:

 - **Brush your teeth with toothpaste** for two minutes (at least 1h after eating) including outer/inner teeth  surface and against the gumline (sweep or roll the brush away from the gumline).
 - **Use dental floss** after brushing to remove plaque between teeth and under the gum line, where ordinary toothbrushes can't reach.
 - **Use mouthwash liquid** which can kill 99.9% of bacteria and provides protection against plaque (such as Listerine). Alternatively use water or an acid-neutralizing mixture (one part baking soda, eight parts water).
 - You may add **activated charcoal powder** onto your toothpaste. It absorbs toxins, a wide variety of drugs, chemicals and other impurities.
 - **Never brush immediately after an acidic meal or drink.** Always wait at least 30 minutes.
  It is recommended to brush your teeth at least 1h after eating or drinking acidic foods/drinks to prevent chance of [enamel erosion][1] and [dental erosion][2] which can damage your teeth. So **brushing too soon after meals and drinks can do more harm than good.** See: [Really? Never Brush Your Teeth Immediately After a Meal][3]

 - After your last teeth brushing, **avoid eating and drink only plain water** (maintaining the right pH and °C in the mouth can prevent a dental plaque, which can help saliva to naturally neutralize the acids produced by the bacteria and remineralize the tooth surface).
 - You may use **Plaque Disclosing gel** or **Disclosing tablets** which can dramatically highlights harmful bacterial plaque on tooth surfaces and shows the areas where more brushing and flossing are required. See: [Detection of plaque build up][4].
 - For a better whitening, add a baking soda. According to [Wikipedia][5], toothpaste containing sodium bicarbonate has in several studies shown to have a better whitening and plaque removal effect than toothpastes without it. If your whitening toothpaste isn't working, try leaving it on your teeth for a couple of minutes before you rinst it off.
