What problems could arise with a dental crown?
牙冠可能出现什么问题？
Tooth sensitivity
After the anaesthetic starts to wear off, it is normal to feel some sensitivity or discomfort in your crowned tooth. Toothpaste made for sensitive teeth can be used to reduce the effects.
However, if you experience pain or sensitivity when you chew, the crown may be placed too high. Consult your dentist to have it fixed.
Chipped crown
Crowns made of porcelain are more prone to chipping than other materials. When this happens, resin can be used to fill the chip temporarily if it is small. If the chip is huge, consult your dentist to get it replaced.
>Loose or falling off of crown
At times, the crown may become loose as the cement disintegrates from under the crown. This allows bacteria to enter which will lead to tooth decay. In such cases, you are advised to consult your dentist if your crown feels loose.
If your crown falls off, contact your dentist immediately for temporary measures before your consultation. During the appointment, he will either re-cement the existing crown or make a new one.
牙齿敏感
麻醉剂开始消退后，你的牙冠会感到一些敏感或不适，这很正常。可以使用为敏感牙齿制作的牙膏来减少影响。
但是，如果你在咀嚼时感到疼痛或敏感，则可能是牙冠放置得太高了。请咨询你的牙医，把它修好。
树冠脱落
瓷器制成的牙冠比其他材料更容易出现缺口。当发生这种情况时，如果缺口较小，可以用树脂暂时填补。如果缺口很大，请咨询你的牙医，把它换掉。
>Loose or falling off of crown
有时，由于水泥从牙冠下瓦解，牙冠可能变得松动。这允许细菌进入，从而导致牙齿腐烂。在这种情况下，如果你的牙冠感觉松动，建议你咨询你的牙医。
如果您的牙冠脱落了，请在就诊前立即与您的牙医联系，以采取临时措施。在预约期间，他将重新加固现有的牙冠或制作一个新的牙冠。
