How can I recover my tables in sql server database
Yes, as Iren and Rahul said, you can use ApexSQL tools. If the tables were dropped, ApexSQL Recover can recover them even from databases in the simple recovery model. ApexSQL Recover can recover both table structure and table records 

On the other hand, ApexSQL Log cannot recover records lost when a table was dropped, it can only recover the table structure

In case the records that were lost using DELETE (not DROP TABLE), both ApexSQL Log and ApexSQL Recover can help

The advantages of ApexSQL tools over recovery to a point in time is that ApexSQL will recover just the tables you specify (creates CREATE TABLE and INSERT INTO scripts) , while a point-in-time recovery will roll back all the transactions that happened in the meantime

A DROP TABLE statement marks the MDF file pages used by the dropped table for deallocation. These pages are actually still in the MDF file until overwritten by new operations. To prevent new operations overwrite the data necessary for successful recovery, we recommend creating a copy of the original MDF and LDF files immediately
