If this option is too expensive for you, there are cheaper alternatives to a dental implant crown, including, but not limited to, tooth extraction and large composite filling.
Large composite fillings. This is an inexpensive and relatively non-invasive option. However, fillings are not considered durable and your tooth cusps will not be supported.
Tooth extraction. The last solution would be to have your tooth extracted. This is considered the cheapest alternative to a dental crown but is also the least desirable.
